Question

definr potential difference​

Answer 1

Answer:

If the electric potential difference between two locations is 1 volt, then one Coulomb of charge will gain 1 joule of potential energy when moved between those two locations. Because electric potential difference is expressed in units of volts, it is sometimes referred to as the voltage.

Answer 2

POTENTIAL DIFFERENCE - DEFINITION

Potential difference between two points is the work done in moving a unit positive charge between the two points. Its unit is V (Volts).

VAB =VA−VB = W AB/Q

WORK DONE BY A GIVEN CHARGE - RESULT

Work done by a charge to move through a potential difference V is given by W=Q(Vf −Vi).

Where Vf = Final potential and

Vi = Initial potential

UNIT OF POTENTIAL DIFFERENCE - DEFINITION

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.
