In the circuit of Figure $\mathrm{P} 21.57$, the switch $\mathrm{S}$ has been open for a long time. It is then suddenly closed. Determine the time constant (a) before the switch is closed and (b) after the switch is closed. (c) Let the switch be closed at $t=0 .$ Determine the current in the switch as a function of time.

Step 1
The time constant $\tau$ for this circuit is given by the equation $\tau = \frac{L}{R}$. So, to determine the time constant before the switch is closed, we need to know the values of $L$ and $R$. Show more…

In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take ε = 10.0 V, R1 = 58.0 kΩ, R2 = 150 kΩ, and C = 12.0 μF. (a) Determine the time constant before the switch is closed. (b) Determine the time constant after the switch is closed. (c) Let the switch be closed at t = 0. Determine the current in the switch as a function of time. (Assume I is in A and t is in s. Do not enter units in your expression. Use the following as necessary: t.)
