Answer:
The electricity we get from batteries is known as direct current (DC). Unlike the electricity we receive from power outlets, which is alternating current (AC), batteries produce a steady flow of electrons in a single direction. This means that the flow of electric charge in a battery remains constant and does not change direction periodically like AC.
Batteries work through a chemical reaction called an electrochemical reaction. Inside a battery, there are two electrodes: a positive electrode called the cathode and a negative electrode called the anode. These electrodes are usually made of different materials, such as zinc and copper.
When a battery is connected to a circuit, a chemical reaction occurs between the electrolyte (a solution or paste inside the battery) and the electrodes. This reaction releases electrons at the anode and attracts them towards the cathode. The flow of electrons from the anode to the cathode through the circuit creates an electric current.
To summarize, the electricity we get from batteries is direct current (DC), which flows in a single direction. This is because batteries use a chemical reaction to produce a steady flow of electrons from the anode to the cathode
