What is potential difference? Explain and give its unit with definition​

Answer 1

Answer:

the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.

The S.I Unit of potential difference is volt (V). 1 volt =One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other. The potential difference is measured by an instrument called voltmeter.

Answer 2

Hey mate,

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. ... The energy is transferred to the electrical components in a circuit when the charge carriers pass through them. We use a voltmeter to measure potential difference (or voltage).

Hope it helps.
