Problem

In the steady state condition, the rate of heat produced in a choke coil is

P

. The time constant of the choke coil is

\tau

. If now the choke coil is short-circuited, then the total heat dissipated in the coil is (a)

P\tau

(b)

\frac{1}{2}P\tau

(c)

\frac{P\tau}{\ln 2}

(d)

P\tau \ln 2
