An electrical generator is a machine that helps create electricity for us to use. It works kind of like a bicycle- when you pedal a bicycle, it creates energy that makes the wheels turn. Similarly, an electrical generator creates energy using mechanical power, usually from a fuel like coal, natural gas, or water.
The energy created by the generator can then be transferred to power things like lights or appliances in homes, businesses, or even an entire city. It's important to note that while generators produce electricity, they don't store it, so the energy they create must be used right away or it'll be lost.
Overall, electrical generators are super helpful and allow us to use electrical devices and services every day!
