The magnetic flux through a coil perpendicular to the plane is given by Φ = 5t³ +4t² +2t calculate the induced emf through the coil at t = 2S

A circular coil of radius 8.0 cm and 20 turns rotated about its vertical diameter with an angular speed of 50 rads in a uniform horizontal magnetic field of magnitude 3 X 10^-2T. Obtain the maximum and average emf induced in the coil if the coil forms a closed loop of resistance 10Ω then calculate the average power loss due to joule heating.

In the circuit diagram shown in figure, R = 10W, L = 5H, E = 20V. I = 2A. This current is decreasing at a rate of -1.0A/S. Find VAB at this instant.

An AC generator consists of a coil of 1000 turns and cross sectional area of 100 cm2, rotating at an angular speed of 100 rpm in a uniform magnetic field of 1.6 x 10^-2 T calculate the maximum emf produced in the coil.

The instantaneous current from an AC source is given by I = 5 sin 314 t. What is the rms value of the current?
