In $($Figure $1),$ suppose that EE $=58\mathrm{.}0$ VV$,$ RR $=240\mathrm{.}0$ and LL $=0\mathrm{.}150$ HH$.$ With switch S$2$S$2$ open, switch S$1$S$1$ is left closed until a constant current is established. Then S$2$S$2$ is closed and S$1$S$1$ opened, taking the battery out of the circuit. What is the initial current in the resistor, just after S$2$S$2$ is closed and S$1$S$1$ is opened? What is the current in the resistor at tt $=4\mathrm{.}10104$ ss$?$ What is the potential difference between points b and c at tt $=4\mathrm{.}10104$ ss$?$ Which point is at a higher potential? How long does it take the current to decrease to half its initial value?
