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?

 

In the circuits in Figures P19.67, P19.70, and P19.72, assume the resistance values are R₁ = 1500Ω and R₂ = 2400 Ω, and with capacitances C₁ = 45 μF and C₂ = 25 μF. The emf is ε = 5.5 V. The switches are labeled S.
