Here are four examples of **alternating current (AC)**:
1. **Power supplied to homes (Utility Power)**:
* The electricity that powers most homes and businesses comes from power plants and is in the form of AC. The voltage alternates between positive and negative values, which is how it can travel efficiently over long distances.
2. **Electric Generators**:
* AC is generated by machines called alternators, which convert mechanical energy (from turbines, for example) into electrical energy. These are used in power plants and backup generators.
3. **Electric Motors in Appliances**:
* Many household appliances, like fans, refrigerators, and air conditioners, use AC motors. These motors rely on the alternating current to produce rotational motion.
4. **Transformers**:
* Transformers, which are used to step up or step down the voltage of electricity, work with AC. They rely on the alternating nature of current to transfer energy between coils of wire.
These are all practical examples of how AC is used in our daily lives!
