Within a battery connected in an electric circuit, the charge (assumed to be positive)
Options
- Aalways moves from the positive terminal to the negative terminal
- Bmay move from the positive terminal to the negative terminal
- Calways moves from the negative terminal to the positive terminal
- Ddoes not move at all
Correct answer
B. may move from the positive terminal to the negative terminal
Step-by-step solution
When a battery is discharging in a circuit, it acts as a source of electrical energy. In this case, positive charge moves from the negative terminal to the positive terminal inside the battery due to internal chemical forces.
When the battery is being charged by an external source, the direction of current is reversed. In this case, positive charge moves from the positive terminal to the negative terminal inside the battery.
Thus, within a battery, positive charge may move from the positive terminal to the negative terminal depending on whether it is charging or discharging.
