Potential of a conductor changes on charging.
a. How is charge related to the potential?
b. What is the ratio called?

Text Solution

Verified by Experts

a. On charging a body its potential rises. The potential of the body is proportional to the quantity of charge.
b. `V alpha Q or V=Q/C therefore C=Q/V` It is called capacity.
