In $($Figure $1),$ suppose that EE $=68\mathrm{.}0$ VV$,$ RR $=250\mathrm{.}0$ and LL $=0\mathrm{.}160$ 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. Part E

How long does it take the current to decrease to half its initial value?
