kse koi send krega yaha pr........

Answer 2

Electric potential is the work done per unit charge in bringing the charge from infinity to that point against electrostatic force.

In a conductor, electrons flow only when there is a difference in electric pressure at its ends. This is also called potential difference. In a circuit, this potential difference is created by a battery.
A battery or a cell has a potential difference due to reaction of chemicals inside it even when it is not connected to any circuit. Once connected, the potential difference makes the electrons flow and the current is generated in the circuit/conductor. A battery generates this potential difference till the chemicals inside it are not completely spent.


Potential difference is also defined as work done to move a unit charge from one point to another.

V = W/QOrPotential difference =Work done/Charge
