Problem 3 R? L + V_A ? R? The switch has been closed for a long time. At t=0 s it opens. V_A=10 V, R?=1 k?, R?=100 k?, L=1 mH. (A) What is the voltage over R? at t=0? s? (B) What is the time constant ? for the inductor to release its stored energy?

However, since the inductor opposes changes in current, it will try to maintain the current flowing through it. This means that initially, the current through the inductor will remain the same. Using Ohm's Law, we can calculate the current flowing through the Show more…

In the circuit, switch $S$ is opened at $t=0$ after having been closed for a long time. (a) How much energy is stored in the inductor at $t=0 ?$ (b) What is the instantaneous rate of change of the inductor's energy at $t=0 ?$ (c) What is the average rate of change of the inductor's energy between $t=0.0$ and $t=1.0 \mathrm{s} ?(\mathrm{d})$ How long does it take for the current in the inductor to reach 0.0010 times its initial value?

In Fig. 30.11, switch $S_1$ is closed while switch $S_2$ is kept open. The inductance is $L = 0.115$ H, and the resistance is $R = 120 \, \Omega$. (a) When the current has reached its final value, the energy stored in the inductor is 0.260 J. What is the emf $\varepsilon$ of the battery? (b) After the current has reached its final value, $S_1$ is opened and $S_2$ is closed. How much time does it take for the energy stored in the inductor to decrease to 0.130 J, half of the original value?
