Recall / Warm-Up

Conventional current in a circuit flows in which direction?

From the positive terminal to the negative terminal (from high to low potential).

From the negative terminal to the positive terminal (from low to high potential).

In the same direction as electron flow.

Conventional current has no defined direction — it depends on the circuit.
