Shown in the figure is an R-L circuit. Just after the Key (K) is closed

Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c, d)
The current in the circuit at the instant of closing the Key
is equal to
. Current at any time in transient state is given as

The voltage drop across the inductor is
that oppose the applied emf E

Since the circuit current is zero, the heat loss (proportional to
) will be zero
