Difference Between Volts and Watts

As we know, Volts and watts 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 Volts:

A volt is describing that the potential difference between two points of a conducting wire carrying a constant current of 1 ampere when the power dissipated between these points is equal to 1 watt. The symbol of a volt is V.

Definition of Watts:

A watt has expressed the rate of power flow. When one amp flow through an electrical difference of one volt, its result is expressed in terms of watts. W is the symbol for watt or watts.

One of the major differences between the volts and watts is that the volt is the SI unit of electromotive force and potential difference while in the watts measure the SI unit of power. Here this article gives information about the difference between volts and watts to better understand this topic.

The main key difference between volts and watts are listed below:

  • The SI unit of electromotive force and potential difference, whereas the watt is the SI unit of power.
  • The symbolic representation of volts is V and the watt is represented by the symbol of W.
  • The formula of the volt is potential energy/ charge, Formula of watt is volt*current.
  • In volts, a small amount of power is measured whereas watt measures the real power utilizes by the electrical devices.
  • The reading takings in volt are easier as compared to watts because the main reason that watt requires both the quantities of voltage and current.
  • The value in volts is measured by the voltmeter whereas the watt is measured by the power meter.
  • The reading taking of volts is very easy when compared to watts while the reading taking of watts is difficult since it required quantities of both voltage and current.
  • Volt describes a small portion of voltage from the power source, watts gives a more realistic measurement for power.
  • The base unit of watt us KgM2S-3 and the base unit of a volt are KgM2A-1S-3. The base unit is the fundamental unit that is not combined with any other unit examples- meter, kilogram, ampere, etc.
  • The power supplies and batteries often show how many volts it provides but not how many watts.
  • Volt is derived a portion of the power source while the watts can give you a more realistic measurement.
