A circuit includes a resistor placed between the positive terminal and the negative terminal of a power supply. Which row shows the direction of conventional current and the direction in which free electrons move in the resistor?
- Aconventional current: from negative to positive; free electrons: from negative to positive
- Bconventional current: from negative to positive; free electrons: from positive to negative
- Cconventional current: from positive to negative; free electrons: from negative to positive
- Dconventional current: from positive to negative; free electrons: from positive to negative
