JEE Advanced 2020 Solutions: AmBIGuous Mutual Inductance Problem

Описание: DON'T MISS THE 2 PRACTICE PROBLEMS ON Mutual inductance AT THE END OF THE VIDEO. LEARN THE BEST WAY TO COUNTER THIS PROBLEM IN EXAM CONDITIONS. WHY DID JEE GIVE A FINAL KEY OF 55 INSTEAD OF 35? THE ANSWER LIES IN THE LUCID EXPLANATION OF CONCEPT/SOLUTION IN THE VIDEO . HOW TO CHOOSE THE SIGN OF MUTUAL EMF INDUCED ?
Q : The inductors of two LR circuits are placed next 10 each other,as shown in the figure. The values of the If-inductance of the inductors. Resistances, mutual-inductance and applied voltages are specified in the given circuit. After both the switches are closed simultaneously, the total work done by the batteries against the induced EM F in the inductor by the time the currents reach their steady state values_________mJ
