Question

what is potential difference?​

Answer 1

Answer:

voltage electric potential difference ,eletrical pressure is difference in electric potantial between two Points

Answer 2

Potential difference

The potential difference is the amount of work done on carrying a unit charge from one point to another point of a conductor

Define the SI unit of potential difference

The SI unit of potential difference is measured by the amount of work done ( 1 joule) on carrying 1 coulomb charge from one point to another across the conductor

SI unit => $\large\rm \frac{Work}{Charge}$

=> $\large\rm \frac{J}{C}$ $\rm \: or \: JC^{-1}$

=> Volt (represented by V)

Cell or battery

Cell is a device that provides potential difference to the current carrying conductor.

A group of cells is known as battery. More the cells, more the potential difference.
