Difference between ammeter and voltmeter | Ammeter vs Voltmeter

Ammeter and voltmeter are electrical instruments and need electricity as well as a complete electric circuit to display reading. The main key difference between the ammeter and voltmeter are discussed in this tutorial on the basis of certain important factor such as connection with some uses, safety, resistance, ideal behaviour, measuring units, applications, etc. 

Before we learn about the key difference between ammeter and voltmeter first let us understand the definition of ammeter and voltmeter. 

Definition of ammeter: 


The ammeter is measuring the instrument which is used to measure the current in the circuit.  It measures the small amount of current in must in mA or in microampere. The ammeter is placed in series with the measuring circuit so that the whole current of the circuit passes through it.

Definition  of voltmeter:


The voltmeter is the voltage measuring device. It is basically connected in parallel with the electrical circuit whose potential is to be measured. The connection polarity of the voltmeter is the same as that of the ammeter.

The main key difference between ammeter and voltmeter are given below.
  • The ammeter is defined as the device used for measuring the small value current flow in the circuit, while in voltmeter measure the potential difference between any two points of the electrical circuit. 
  • The ammeter representation of an ammeter circuit with A while in voltmeter the circuit denoted by a circle with V inside it.  
  • The ammeter measures the current in amperes or even smaller units mA or microampere while in voltmeter measures the difference in volts. 
  • The accuracy of the ammeter is much more as compared to the voltmeter.
  • The measuring range of the voltmeter can be increases or decreases by changing the value of resistance whereas the rage of ammeter can not be changed.
  • The resistance of the ammeter is low while the internal resistance of the voltmeter is very low so that the current from the circuit does not disturb the measuring of the voltmeter. 
  • The ammeter is connected in series with the circuit for measuring the complete current whereas the voltmeter is connected in parallel with the circuit.  
  • In ammeter, a large amount of current passes through while in voltmeter is a very small amount of current passes.
  • In ammeter low resistance to electricity so must not e connected straight across the supply while in voltmeter high resistance to electricity so e able to be connected across the supply.
  • The resistance of an ideal ammeter is zero but in resistance of an ideal voltmeter is infinity.
  • The circuit must be disconnected from the power source in order to attach the ammeter while in voltmeter circuit does not need to be disconnected to attached the voltmeter.
  • An ammeter can be created by attaching a small resistance in parallel with the galvanometer whereases in voltmeter can be created by attaching a very high resistance in series with the galvanometer.

Difference between MPCB and MCCB

Motor protection circuit breakers ad moulded case circuit breakers both are low voltage AC circuit protection devices. It is used to open and close the circuit manually and interrupt the circuit automatically on the occurrence of faults. MPCB and MCCB both are used to protect against overload and short circuits. Here any query regarding this topic please give a comment below as well as any opinion regarding this topic please inform me in the comments section.

Difference between MPCB and MCCB :

  • MPCB stands for motor protection circuit breaker while in MCCB stands for molded case circuit breaker. 
  • MPCB is used to manually turn on and off electric motors and at the same time protect them from different types of faults occurring in motors while in MCCB are used in power distribution and low voltage distribution circuits as well as motors loads.
  • MPCB is specially designed for motor protection while in MCCB are specially designed for general-purpose circuit protection.
  • MPCB can protect the motor against overload, short circuit, phase loss, and under-voltage faults while in MCCB can protect the motor against overload and short circuits. This circuit can also provide under-voltage, earth faults, and phase failure faults but these features are made available with additional accessories.
  • MPCB can withstand the stating currents without interrupting the circuit while in MCCB is used as backup protection for a motor, it may interrupt the circuit if it is selected based on its full load current.
  • MPCB is maximum load current can be set based on the full load current of the motor while in MCCB is overload, short circuit and trip relay delay time can be set based on the applications.
  • MPCB is selected based on the full load current of motors and maximum possible short circuit current while in MCCB are selected based on the maximum current and maximum short circuit current interrupt safety. 
  • MPCB has an adjustable bimetallic strip for overload protection. this strip can be adjusted between two set values but the MCCB overload value of MCCB can be  40% to 100% of its rated value.
  • MPCB can protect a motor against overload and short circuit while in MCCB when used in motor protection circuit can protect against short circuit only. Hence additional overload relay and contactor.
  • A motor can be directly ON and OFF manually using an MPCB, the contactor is optional while in  MCCB contactor is a must in these cases.
  • Some MPCB comes with auto-resetting features that allow motors to resume its operation after a short period from the occurrence of overload trip while in MCCB is feature is not available.
  • Overload relay is not required for motor circuits with MPCB backup but in MCCB overload relay is required.
  • Some MPCB comes with an auto-resetting feature that allows motors to resume its operation after a short period from the occurrence of an overload trip while in MCCB feature is not available.

Difference between ammeter and ohmmeter

An ammeter is an instrument used to measure the current through a circuit is connected in series with the component through which the current is to be measured whereas voltmeter is an instrument used to measure the voltage across the two ends is connected across the end of component across which the voltage has to be measured. Let us have a deep insight into the definition of ammeter, ohmmeter and key difference between them in this article. 

Definition of ammeter:

An ammeter has used for measuring the current in an electronic circuit. Electric currents are measured in amperes, hence the component which measure current is known as an ammeter. It is used to measure smaller currents, in the milliampere or microampere range.

Definition of ohmmeter:

An ohmmeter measures the basically resistance and also a continuity of electrical circuit and their components. The unit of resistance is ohms Ω

Difference between ammeter and ohmmeter:

  • The ammeter measures current while ohmmeter measures resistance.
  • The ammeter is connected in series but in ohmmeter is connected in parallel.
  • In ammeter, the current is measured in amperes while ohmmeter is an electrical instrument that measures electrical resistance in ohms. 
  • Ammeter used to measure smalled currents in the milliampere or some microampere range are designated as millimetres or micrometres while in micro ohmmeter is used low resistance measurement while Megaohammters measure the large values of resistance. 
  • While using an ammeter positive ad negative terminal need to be aligned with a circuit, while checking current, we do not need to take care of positive ad negative terminals while calculating resistance in an ohmmeter. 
  • The ohmmeter is very convenient the use but less accurate compare to an ammeter.
  • An ammeter is four of type permanent moving coil ammeter, moving iron ammeter, electrodynamometer ammeter, rectifier type ammeter while in ohmmeter is of three types series ohmmeter, shit ohmmeter ad multi range ohmmeter, this is the type of construction while in current category there are two types AC ammeter and DC ammeter.

Difference between MCB and RCBO

MCB stands for miniature circuit breaker while RCBO stands for a residual current circuit breaker with overload protection, this both are circuit protection devices. These devices are most commonly used in the distribution board in the office, home, theatre, commercial building, low voltage power distributions, etc.

What is MCB?


MCB is designed to operate on overload current and they can be used as protection devices for the individual circuit. MCB can also provide magnetic fault protection and short circuit protection.

What is RCBO?


As the name suggests the operating fundamental of RCBO is to operate on residual as well as overload current. RCBO is a combination of MCB and RCCB. When in some current imbalance occur the RCCB will operate ad when there is overload in the circuit breaker will operate.

Difference between MCB and RCBO :

  • MCB stands for miniature circuit breaker while RCBO stands for a residual current circuit breaker with overload protection.
  • MCB can provide protection against overcurrent and short circuit only while RCBO can provide protection against overcurrent and earth leakage.
  • MCb can not protect against earth faults while in RCBO can protect against earth fault, electric shocks that MCB may not do.
  • MCB is selected based on the load, the maximum short circuit during overload and short circuit,  RCBO is the combination of MCB and RCCB. It is selected based on the load and maximum short circuit current it ca interrupt, trip curve and maximum leakage current.
  • MCB is used to protect lighting circuits, air conditioners and other home applications RCBO is used for protection against electric shocks. Hence it is mainly used to interrupt the power to water heaters, power sockets, etc. 
  • MCB is monitoring the current flow through the line and interrupts the circuit during overload and short circuit, while RCBO is not only monitoring but the current flow through the line interrupt the circuit during overcurrent, short circuit, and earth leakage.
