प्रश्न
In an electric circuit containing a battery, the charge (assumed positive) inside the battery ____________ .
विकल्प
always goes from the positive terminal to the negative terminal
may go from the positive terminal to the negative terminal
always goes from the negative terminal to the positive terminal
does not move
उत्तर
may go from the positive terminal to the negative terminal
In the study of electric current, the direction opposite the flow of electrons is regarded as the direction of flow of positive charge. In a battery, positive charge flows from the negative terminal to the positive terminal when it is discharging (connected to external circuit). But when the battery is charged, the positive charge flows from the positive terminal to the negative terminal.
