The figure below shows a circuit consisting of a 12.0 V battery in series with an inductor with inductance L = 11.0 H, a resistor with resistance R = 7.00 Ω, and a switch, initially open. (a) After the switch is closed, what is the maximum current (in A) that will flow through the circuit?   b) What is the time constant (in s) of the circuit?   (c) After the switch is closed, how much time (in s) does it take for the current to reach 95.0% of its maximum value?
