inductor

Morty, I need darkness to prime these optical inductors.

Because, remember, the inductor opposes the change in current with its own changing magnetic flux.

So after the battery is removed, the inductor generates its own current!

There's no longer a changing current, so the inductor acts just like a piece of wire.

So, inductors oppose a change in current, whether it's an increase or a decrease.

So let's sum up: Current in inductors lags voltage.

So to get a handle on how inductors work, let's first consider one in a DC circuit.

Let's say this circuit has an inductor connected in series with a battery that has a constant voltage, V naught.

For example, how are alternating currents affected when you add resistors? Or capacitors? Or an inductor?

For inductors and capacitors, however, the story's a little different.
