Question

Define potential difference of a cell.......

Answer 1

Answer:

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).

Answer 2

the potential difference between two points is equal to the work done per unit charge in moving a positive test charge from one point to other

the potential at a point is defined as the amount of work done per unit charge in bringing a positive test charge from infinity to that point

1 volt is equal to 1 joule by 1 coulomb
