Batteries are important because they provide power in electrical circuits. They do this by changing stored chemical energy into electrical energy. Here’s a simple breakdown of how batteries work:
Chemical Reactions: Inside a battery, special reactions happen that create tiny particles called electrons.
Voltage: Most batteries, like AA batteries, have a voltage of 1.5 volts. Car batteries can have a voltage of up to 12 volts.
Current Flow: When electrons move, they create electric current, which we measure in units called amperes (A).
When a circuit is closed (meaning all parts are connected), the battery creates a difference in electrical pressure. This difference pushes the current through parts like resistors and light bulbs. For example, a regular bulb uses about 0.1 amperes to light up.
