Difference Between Volt and Amp

As we know, Volts and amp are the two most common key terms in the field of electrical and electronics and communication engineering. Most of the times these terms confuse the newbie or those who just started learning the electronics sciences.

Definition of Volt:

The volt is measured by the work done by the electric charge to move from one end to another. It is the unit of the potential difference, electric potential, and electromotive force. The volt is represented by the symbol of V. The subunit of volts is microvolt, megavolt, millivolt.

Definition of Amp:

The ampere is a rate of flow electric charge flow through the conductor. The SI unit of electric current. It represented by the symbol of A. 

One of the major differences between the volt and amp is that the volt is the SI unit of the voltage, electromotive force, potential difference whereas the amp is the SI unit of the current. Here this article gives the difference between volt and amp to better understand this topic.

The main key difference between volt and amp are listed below:

  • The volt has measured the force which causes the electrons to flow through the conductor whereas the amp measures the rate of flow electrons.
  • Volt and amps are correlated by ohm's law.
  • The volt represented by the symbol, of V and the ampere is represented by the symbol of A.
  • Power sources are often labeled by how many volts it has but while you can only get the number of amps when you can apply the power source to the circuit.
  • Volt is equal to the ratio of joule/coulomb whereas the amp is represented by the Coulomb/second,
  • The volt is the unit of potential difference, Voltage and electromotive force whereas the amp is the unit of current(I).
  • Most of the batteries have a fixed voltage but their ampere varies with higher amperage batteries lasting longer.
  • The volt is measured by the voltmeter whereas the amp is measured by the ammeter.
