Explain the working of a lead-acid accumulator.

Open in App

Solution

In a lead-acid accumulator, the anode and cathode are made of lead dioxide and lead respectively. The electrolyte is dilute sulphuric acid. As power is discharged from the accumulator, both the anode and cathode undergo a chemical reaction that progressively changes them into lead sulphate. When the anode and cathode are connected by a wire, current flows from anode to cathode through the wire.
