A pair of identical secondary coils S1 and S2 are wound on the same core and connected in series so that their induced electromotive forces add. The current in the primary is Ip=10sin(100πt)A. Each secondary coil has a mutual inductance of 200mH with the primary.
(i) Write the expression for the instantaneous electromotive force induced in each secondary coil.
(ii) Calculate the peak value of the net electromotive force across the series combination of S1 and S2."
