Explanation / Answer

part c) long time after switch is closed

inductor will behave as a short circuit

=> net resistance of the circuit Req = R + 2R*R/(3R) = 5R/3 = 5*65/3 = 108.333 ohm

SO current I = E/Req = 5.4/108.33 = 49.8 mA

part b) charateristic time constant T = L/Req = 36*10^-3/108.33 = 332.31*10^-6 sec

=> interval of two time constant => t = 2T = 664.62*10^-6 sec

I = Io*(1 - e^(-t/T))

=> I = 49.8*10^-3*( 1 - e^(-2)) = 43.077 mA
