1. A series RL circuit containing a 0.17-H inductor has a time constant of 0.13 s. What is the resistance in the circuit? 2. A 1000-ohm's resistor is joined in series with a 400-mH inductance and a 12-V battery. (a) What is the time constant of the circuit? (b) How long will it take after the circuit is completed for voltage
