Whats the formula for power flowing through an inductor in a LR circuit that is decaying?

Question

In a simple L-R circuit after the circuit has been exposed to a DC power supply for some time a switch is employed to remove it from the power supply to a short circuit. Whats the formula for the power flowing in the inductor in terms of I(t) and R

Answer 1

The circuit has a time constant which is calculated as
T=L/R

The circuit will have the equation
for current of:

i(t)=(Vs/R)*e^(-t/T)
Where
Vs is the supply voltage
e is Euler's constant
