Question

What do you understand by electric potential? Derive an expression for electric potential. I) at a charged single conductor

Answer 1

Explanation:

ELECTRIC POTENTIAL AT A POINT:

Amount of work done ( ext. agent ) per unit charge in bringing the charge from infinity to that point without change in kinetic energy.

Derivation refer in Attachment

Note :

Work done by external agent against :

• Electrostatic force is taken

• This work done is independent of path chosen because electrostatic force is conservative force.

• The test charge must be positive and very small so that it cannot create its own field .
