Within a battery connected in an electric circuit, the charge (assumed to be positive)

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
