Question
An emf, ε = 18.0 V, two R = 7.97-02 resistors, and
a L = 5.13-mH inductor are wired to two switches,
S₁, and S₂, as shown in the circuit diagram.
At first S₁ is closed, with S₂ open. A long time
later, S₂ is closed, and S₁ is immediately opened.
1. Switch 1 Open. Switch 2 Closed.
(a) Calculate the time constant of the circuit when S₁ is closed and S₂ is open.
T =
msec
(b) What is the current through the inductor a long time after S₁ is closed?
