What Current Does a Battery Produce? (AC Or DC Current)
Batteries produce direct current (DC). The electrons flow in one direction around a circuit. In a battery, there are two half-cells. Each half-cell has an electrolyte and electrodes. One electrode is the anode, and the other is the cathode. The anode is where oxidation occurs. The cathode is where reduction occurs.
