Question

define potential difference ??​

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.

Answer 2

In short

The potential difference between two points in a circuit is the work done in moving a unit charge (i.e. one coulomb) from one point to the other. The units for potential difference are Joules per coulomb, or volts. (1 volt = 1 Joule/coulomb).

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.

1 Volt=

1 Coulomb

1 Joule

The potential difference is measured by an instrument called voltmeter.
