### Electrostatics of Conductors

Electrostatics of Conductors Conductors contain mobile charge carriers. In metallic conductors, these charge carriers are electrons. In a metal, the outer (valence) electrons part away...

### Potential Energy

Potential Energy in an External Field The potential energy of a single charge: The external electric field E and the corresponding external potential V may vary...

### Equipotential Surfaces

Equipotential surfaces Surface over which the electric potential is same everywhere is called an equipotential surface. Equipotential surfaces...

### Electrostatic Potential

We know that central forces are conservative in nature i.e., work done on any particle moving under the influence of conservative forces does not...

### Applications of Gauss’s Law

Applications of Gauss’s Law Field due to an infinitely long straight uniformly charged wire Field due to uniformly...

### Gauss’s Law

The surface integral of electrostatic field E produced by any source over any closed surface S enclosing a volume V in vacuum i.e. total electric flux over...

### Electric Dipole

An electric dipole is a pair of equal and opposite charges q and –q separated by some distance 2a. Its dipole moment vector p...

### Electric Flux

Consider a plane surface of area ΔS in a uniform electric field E in the space. Draw a positive normal to the surface and...

### Electric Field Lines

For a single positive point charge q, electric field is Since electric field varies as the inverse of the square of...

### Electric Field

Electric Field An electric field is said to exist at a point if a force of electrical origin is exerted on a stationary charged body...
