Electric Potential—

The Electric Potential at a point in an electric field is defined as the amount of work done per unit positive test charge to bring it from infinity to that point against the electrostatic force due to the Electric Field.

            If V is the electrostatic potential at a point A in the electric field of point charge +q and W is the work done in moving it from infinity to that point against

 the electric force.

V=W/q

Its unit is Volt. It is a scalar quality.

Charge (Electric Charge)
Charge is a basic property of matter due to which objects experience electrical force. It is responsible for attraction and repulsion between objects.

Types of Charges

1️⃣ Positive Charge (+)

  • A body has positive charge when it loses electrons.

  • Example: A glass rod rubbed with silk becomes positively charged.

2️⃣ Negative Charge (−)
