Problem : of Assignment Value
Energy stored in an inductor: 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 b
Enter an expression for the power in the inductor.
Part c
Assume that the current is zero at the instant the switch is closed to position a and a short time later the current has increased to a value I Perform an integral of th power to determine how much energy has been transfered to the inductor during this time interval.
Part d
A currentcarrying inductor does not dissipate energy like a resistor does. It stores the energy similar to the way that a charged capacitor stores energy. While the capacitor stores energy in an electric field, the inductor stores energy in a magnetic field. Modify the expression you obtained in the previous step to express the energy stored in an inductor.
