Chapter 30, Problem 30.27(choose chapter or problem)
In Fig. 30.11, suppose that and With switch open, switch is left closed until a constant current is established. Then is closed and opened, taking the battery out of the circuit. (a) What is the initial current in the resistor, just after is closed and is opened? (b) What is the current in the resistor at (c) What is the potential difference between points b and c at Which point is at a higher potential? (d) How long does it take the current to decrease to half its initial value?
