Question # 1
Briefly describe the current through a metallic conductor and drift velocity.
- Ans 1: In a metallic conductor,free electron are in random motion with the speed of several hundred km/s at the room temperature.If the ends of the wire are connected to the battery the free electrons are experience a force and directed to move in the electric field direction.The accelerating electrons keep on colliding with atoms of the conductors and transfer their energy to the lattice with the result that the electrons acquire an average velocity called drift velocity.The drift velocity is of the order of 10-3.A steady current is establish in the wire.

Question # 1
Why does no current pass through Galvanometer in a balanced wheat stone bridge although the keys in the circuit are closed ?
- Ans 1: No current pass through the galvanometer when wheat stone bridge is balanced.Because at this stage ,both the terminals of the galvanometer are at the same potential.Hence no current will flow through it.
