Question
How can lead storage batteries produceelectric current?
Solution
Lead storage batteries, also known as lead-acid batteries, produce electric current through a chemical reaction. Here's a step-by-step explanation:
-
The battery is composed of several cells, each containing lead (Pb) and lead dioxide (PbO2) plates submerged in a sulfuric acid (H2SO4) solution.
-
When the battery is in use (discharging), the sulfuric acid in the electrolyte reacts with the lead and lead dioxide, releasing electrons and forming lead sulfate (PbSO4) on the plates. This reaction also produces water (H2O).
-
The released electrons flow through a circuit, creating an electric
