If `(dphi_E)/dt` is the rate of change of electric flux, then why is the quantity `epsilon_0 (dphi_E)/dt` is called the displacement current?

How is induced e.m.f related to the rate of change of magnetic flux?

If the rate of change of current in primary coil is doubled,the induced e.m.f. in secondary coil will become

A coil of area 0.75 m^2 and 1000 turns is kept perpendicular to a magnetic field of 0.15 Wb//m^2 . Calculate the change in magnetic flux through the coil when it isrotated through an angle of 30^@ about a diameter.If the time taken for the rotation is0.5s.What is the average value of e.m.f.induced in the coil?

Complete the paragraph: in physics, square is the rate of doing work or, i.e., the amouth of energy trasferred or converted per unit time. In the international system of Units, the unit of power is the square , equal to one square per second. Power is a square quantity that requires both a change in the physical system and a specified tiem interval in which the change occurs. But more square is needed when the work is done in a shorter amount of time.

A current 10 A in the primary of a transformer is reduced to zero at the uniform rate of 0.1 second. If the co-efficient of mutual inductance is 3H, what isthe e.m.f. induced in the secondary and change in the magnetic flux per turn in the secondary if it has 50 turns?

The mutual inductance between the two coils is 2 xx 10^-2 H.Due to the change of current in first coil, an e.m.f. of 1.0 xx10^-2 V is induced in the second coil. Find the rate of change of current in the first coil

A physical energy of the dimension of length that can be formula cut of c,G and (e^(2))/(4 pi epsilon_(0)) is [ c is velocity of light G is universal constant of gravilation e is change

. The magnetic flux through a loop of resistance 0.1Omega is varying according to the relation phi=6t^2+7t+1 , where Omega isin milliweber and t is in second. What isthe e.m.f.induced in the loop at t =1s and the magnitude of the current?

State Faraday,s laws of electromagnetic induction .Prove theoretically, the relation between e.m.f.induced and rate of change of magnetic flux in a coil moving in a uniform magnetic field.

The average e.m.f. induced in a coil in which the current changes from 2 ampere to 4 ampere in 0.05 second is 8 volt. What is the self inductance of the coil?
