An RL circuit includes a basic switch. In position $"$a$",$ the battery, resistor and inductor are connected in series. In position $"$b$",$ the battery is replaced with a short. Two voltmeters and an ammeter have been added to the circuit.

$$ Part $($a$)$

The switch is moved to position $"$a$",$ and current begins increasing. At any given instant in the process, let II represent the current flowing through the ammeter. Enter an expression for Kirchhoff's Loop Rule where the sum of the voltage changes totals zero.
