A substance with less number of free electrons is said to be good conductor.

In diamond, the number of free electrons are:

What are the possible paths of free electrons inside the conductor ?

The number of free electrons is Si at normal temperature is

Mobility of free electrons in a conductor is

Two conductors of equal volumes having non-uniform cross-section are joined as show in figure. The number density of free electrons is more in conductor 2. As current passes through the system. Which of the following option is correct ?

Assertion : Good conductors of electricity are also good conductors of heat due to large number of free electrons. Reason : It is easy to conduct heat from free electrons.

Define drift velocity and relaxation time, with reference to the free electron theory of conductors.

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

A current of 4.8 A is flowing in a conductor the number of electrons passing per sec through the conductor will be

A conductor has been given a charge -3 xx 10^(-7) C by transferring electron. Mass increase (in kg) of the conductor and the number of electrons added to the conductor are respectively
