A motor with a coil that has a series resistance of 100 ohm and an inductance of 30H is powered by a 120 V DC generator. To prevent damage to the motor, a 300 ohm field discharge resistor is connected in parallel with it, as seen in Figure 1. The switch opens at t = 0 s after being in the closed state for a considerable amount of time. Find the voltage at 120 ms through the motor resistor (i.e 100 ohm )..
