After being closed for a long time, the switch S in the circuit shown in the figure below is thrown open at
t = 0. In the circuit, emf = 24.0 V, RA = 4.10 kΩ, RB = 6.80 kΩ, and L = 608 mH.
(a) What is the emf across the inductor immediately after the switch is opened?
(b) What is the common time constant for the two circuits?
