Can current flow in two directions?

1 Answer

Yes, current can flow in two directions, but it depends on the type of current and the circuit setup.

Alternating Current (AC): In AC, the direction of current constantly changes. It flows in one direction, then reverses and flows in the opposite direction. This happens many times per second. AC is the type of current commonly used in homes and businesses for powering devices like lights, appliances, etc.

Direct Current (DC): In DC, current flows in only one direction. This is the type of current you get from batteries or DC power supplies, like those in electronics (phones, laptops, etc.). The direction doesn't change unless the power source itself is reversed.

So, AC current naturally flows in both directions, but DC current stays in one direction unless the power supply changes.
