# Electrostatics of Conductors

Electrostatic Potential and Capacitance
Physics
Class 12

## Overview

Discuss the electrostatic of conductors. Explain that inside conductor, electric field is 0, at the surface of a charged conductor, electrostatic field must be normal to the surface at every point, interior of a conductor has no excess charge in the static situation. Electrostatic potential is constant throughout the volume of conductor and has the same value (as inside) on the surface, electric field on the surface of a charged conductor is E = (sigma / e0) *n^ (outward for positive sigma and inward for negative sigma). Discuss electrostatic shielding. Discuss the earthing of a conductor. Find the mechanical force acting on unit area of a charged conductor. Electric field due to conductors - Problem L1. Solve the equilibrium of charged soap bubble problem. Derive the redistribution of charges taking 2 and 3 plates. Derive redistribution of charges and potential difference taking 2 and 3 shells.
