b) At time t=0 and time= infinity find the current that passes
through the battery
c) What's the time constant for the circuit?
d) What's the back EMF provided by the inductor at t= 1.0
sec?
e) What's instantaneous energy saved in the inductor at time t=
1.0 sec?
f) What is the...

In a series RC circuit, a battery of 7.30 volts is
connected to the resistor of 467 ohms, the capacitor of 6.71
microfarads, and a switch. The capacitor is initially uncharged.
The switch is closed at time t = 0.
How long does it take for the capacitor to get fully
charged? Answer to four decimal places.

At t = 0, a battery is connected to a series arrangement of a
resistor and an inductor. If the inductive time constant is 40.6
ms, at what time (in ms) is the rate at which energy is dissipated
in the resistor equal to the rate at which energy is stored in the
inductor's magnetic field?
