R S2 A 3 H inductor, a 9.75 2 resistor, and a 1.4 V battery are connected as shown above. The circuit also contain two switches, S₁ and S₂. Initially both switches are open. At t = 0 s S₁ is closed while S₂ is left open. a. What is the time constant of the resulting circuit? Submit Answer Tries 0/10 b1. What is the current through the circuit at t = 0 s? b2. What is the current through the circuit after a long time has passed? Submit Answer Tries 0/10 c1. What is the magnitude of the induced emf at t = 0 s? c2. What is the magnitude of the induced emf after a long time has passed? Submit Answer Tries 0/10 d. After the current in the RL circuit has reached its final value (as in b2. above) the positions of the switches are reversed, with S₁ open and S₂. How long does it take for the current to reach a tenth of its initial value?
