What is a common everyday example of a chemical source of electricity?

A battery is a common everyday example of a chemical source of electricity because it generates electrical energy through chemical reactions. Inside a battery, there are two electrodes (a positive and a negative) and an electrolyte that facilitates the movement of ions. When the battery is connected to a circuit, a chemical reaction occurs at each electrode, producing a flow of electrons and thus creating electric current.

Batteries are widely used in various applications, from powering small devices like remote controls and toys to larger systems in vehicles and backup power supplies. Their ability to convert stored chemical energy into electrical energy makes them essential in our daily lives.

In contrast, while generators produce electricity, they do so through mechanical means rather than chemical reactions. Capacitors store electrical energy rather than generating it chemically, and resistors are components that impede the flow of electric current but do not produce or store electricity. This distinction highlights why a battery is distinctly recognized as a chemical source of electricity.
