How is that circuit wont be broken even there is an air gap in between the parallel plates?Ans) In AC circuit capacitor offers resistance to current as aresistor would do in DC. But for DC there exists a current in between the plates called displacement current (it exists everywhere in fact)Id = ε0x dΦe/dtModified amperes law = integral of B.dl = mu0 ( I + Id)there exists a magnetic field between the plates responsible for transfer of charges from one plate to another and hence I= 0but Id is not 0. At every Id = I
(a) Distinguish among metals, insulators and semiconductors on the basis of their energy bands. (b) Why are photodiodes used preferably in reverse bias condition? A photodiode i
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.

a) A circuit has a voltage of 15V and a current of 2A. the phase angle is 45 degree. Verify the true power of the circuit? (Calculate apparent and true power) b) Verify the appare
A transformer is a static device which transfers AC electrical power from one circuit to another at the same frequency but the voltage level is changed usually. When the voltage is
It is the magnetic flux density which still remains in magnetic materials even when the magnetic force is removed. It is measured or calculated in Weber/m 2 .

Calculate the density of sodium metal. The length of the body-centered cubic unit cell is 4.24 A.
TIME OF FLIGHT: "It is the total time for which the projectile remains in air". As, the body goes up and comes back to similar level, so it does not cover vertical distance,
