Consider two windings in a transformer wrapped around as shown in the figure. If the terminals p and q are connected through a mechanism to a battery such that current can flow in both directions then determine the direction of current induced in resistor R for the given conditions:
i) increasing flow of current in winding P from p to q.
ii) decreasing flow of current in winding P from q to p.
iii) increasing flow of current from q to p in winding P.
