Conventional current takes just the opposite direction, from the positive terminal, around the circuit and back to the negative terminal. In that case there’s no charge carrier moving in that ...

The direction of the induced current depends ... This completes this second circuit so current can flow and the motor is switched on. Relays can use a low current in circuit one to switch on ...

and then the current will reverse directions and charge the capacitor back up. The process repeats itself---forever since there is no resistance. Modeling an LC Circuit. It's called an LC circuit ...
