FAQs about Battery discharge current from positive to negative
Does current flow in a battery move from positive to negative?
No, current flow in a battery does not move from positive to negative. Instead, the flow of electric current is conventionally described as moving from the positive terminal to the negative terminal. Electric current is defined as the flow of electric charge.
What happens when a battery is discharged?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode.
