Chapter 30, Problem 27E(choose chapter or problem)
In Fig. 30.11, suppose that \(\varepsilon=60.0\) V, \(R=240\) \(\Omega\), and L = 0.160 H. With switch \(\mathrm{S}_{2}\) open, switch \(\mathrm{S}_{1}\) is left closed until a constant current is established. Then \(\mathrm{S}_{2}\) is closed and \(\mathrm{S}_{1}\) opened, taking the battery out of the circuit. (a) What is the initial current in the resistor, just after \(\mathrm{S}_{1}\) is closed and \(\mathrm{S}_{2}\) is opened? (b) What is the current in the resistor at \(t=4.00 \times 10^{-4}\) s? (c) What is the potential difference between points b and c at \(t=4.00 \times 10^{-4}\) s? Which point is at a higher potential? (d) How long does it take the current to decrease to half its initial value?
