An inductor (L), a resistor (R), a battery (V), and a switch are all connected in a single loop series circuit. Immediately after the switch is closed,

a. The current in the circuit is L/R.

b. the current in the circuit is zero because the inductor resists the change in its current state.

c. The current in the circuit is V/R.

d. The current in the circuit is zero because the circuit contains a resistor.

Murray · Answer 1

An inductor by design will resist a change in current by providing an opposing voltage. This makes it such that after the switch is closed, the current starts at 0 and you will have to wait some time until the circuit reaches its maximum current.
