A RL circuit has a battery attached with a voltage of E=45V,
resistor with R=12Ω and inductance L=30mH. There are two switches
S2 and S1 where S2 can connect to a. S1 closes at t=0s. What is the
time when the self-induced emf of the inductor = -15V. Provide a
response in milliseconds three and show all work.
