A 12.0V dc battery having no appreciable internal resistance, a 146.5? resistor, an 10.6mH inductor, and an open switch are all connected in series.
a) After the switch is closed, what is the time constant for this circuit ?
b) After the switch is closed, what is the maximum current that flows through it ?
c) What is the current 74.0?s after the switch is closed ?
d) After the switch is closed, what is the maximum energy stored in the inductor?
