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.
Electric current is defined as the flow of electric charge. In a battery, this charge consists of electrons, which physically move from the negative terminal to the positive terminal through the external circuit. However, by convention, current is described as flowing in the opposite direction to the flow of electrons.
Confusion about the current direction in batteries arises from the historical convention and the nature of electrical flow. In conventional terms, current flows from the positive terminal to the negative terminal, while electron flow actually moves in the opposite direction, from negative to positive.
It was discovered that if a battery, with its positive side connected to the added electrode (plate), and its negative side connected to the filament (cathode), an electrical current would flow. If the battery was connected the other way around, it was also observed that no current would flow.
Current flow in a battery happens through the movement of electrons. Electrons move from the negative terminal to the positive terminal. This movement creates electronic current. Therefore, the conventional direction of current is considered to flow from positive to negative. This distinction helps understand fundamental electrical concepts.
Originally, current was defined as the flow of charge from positive to negative. Scientists later discovered that current is actually the flow of electrons, from negative to positive. The original definition is now referred to as 'conventional current', to avoid confusion with the newer definition of current.
