Question: Consider again the circuit in Figure P19.70. After switch S 1 is closed for a very long time, switch S 1 is opened and switch

Consider again the circuit in Figure P19.70. After switch S₁ is closed for a very long time, switch S₁ is opened and switch S₂ is simultaneously closed.
(a) What is the current through switch S₂ the instant after it is closed?
(b) Make a sketch of how this current varies with time.
(c) What is the current through S₂ after it is closed for a very long time?
