suppose that E $=50\mathrm{.}0$V $,$ R $=210?$ and L $=0\mathrm{.}140$H $.$ With switch S$2$ open, switch S$1$ is left closed until a constant current is established. Then S$2$ is closed and S$1$ opened, taking the battery out of the circuit.What is the initial current in the resistor, just after S$2$ is closed and S$1$ is opened?What is the current in the resistor at t $=4\mathrm{.}10.$ What is the potential difference between points b and c at t$=4\mathrm{.}4$x$10^-4$
