What0. The circuit arrangement given shows that whenan a.c. passes throughe coil A the current starts flowing in the coil B.(0 State the underlying principle involved.(0) Mention two factors on which the current produced in the coilB depends.Fig. 7.39

Answer»

(i)The circuit operates on Faraday'sprincipalof “mutual induction”, in which an EMF is induced in thecoil B by the magnetic flux generated by the voltages and currents flowing in the coil A.

(ii)It depends on the following factors:-

- ratio of number of turns in coil A and coil B.-voltage applied to coil A.
