Question

A circuit contains a battery, a switch, an inductor, and a resistor connected in series. Initially, the switch is open.

Answer 1

Answer:

a long time after the switch is closed

Explanation:

Energy stored in an inductor is given by

E = 1/2 L i²

A). Before the switch is closed the current in the circuit is zero so energy in inductor will be zero.

B). Inductor opposes the flow of current. It takes some time for current to reach its maximum value. So immedialtly after closing the switch the current  and energy in inductor will still be zero.

C). After closing the switch it takes some time for current to reach its maximum value as inductor opposes the flow of current. so after a long time the current in inductor will reach its maximum value and hence the energy stored will be maximum.
