When an electric field is applied across a semiconductor,

Derive the expression for drift velocity of free electron in terms of relaxation time and electric field applied across a conductor.

Derive the expression for drift velocity of free electron in terms of relaxation time and electric field applied across a conductor.

An electric field us applied to a semiconductor.Let the number of charge carriers be n and the average drift speed be v.If the temperature is increased,

When electric field is applied inside a conductor then free electron are accelerated. Their average velocity in time interval t is proportional to

Which phenomenon occurs when an electric field is applied to a colloidal solution and electrophoresis is prevented?

Assertion : When a potential difference is applied across a conductor, free electrons start travelling with a constant speed called drift speed. Reason : Due to potential difference an electric field is produced inside the conductor, which electrons experience a force.

How does electric current flow along a conductor , when electric field is applied along the length of conductor ?

A charged bead is capable of sliding freely through a string held vertically in tension. An electric field is applied parallel to the string so that the bead stays at rest of the middle of the string. If the electric field is switched off momentarily and switched on

When electric field inside a conductor is E, mobility of free electrons inside the conductor is mu . When the electric field is doubled mobility will be

An alternate electric field of frequency v, is applied across the dees (radius=R) of a cyclotron that is being used to accelerate protons ("mass"=m) . The operating magnetic field (b) used in the cyclotron and the kinetic energy (K) of the proton beam, produced by it, are given by
