Suppose the ends of the coil in the previous problem are connected to a resistance of 100 Ω. Neglecting the resistance of the coil, find the heat produced in the circuit in one minute.

Question

Philoid · Accepted Answer

Given:

Resistance of the coil R=100Ω

Time period T=1min =60s

From previous question induced emf is given by

Current in the coil i is given by

…. (i)

Heat produced in the circuit is calculated by the following formula

Using eqn.(i) we get,

Putting the values of B, A, ω, T and R we have

Therefore heat produced in the circuit in one minute is
