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. |
