A household electrical system is the setup of wires, switches, outlets, and safety devices in your home that bring electricity to your appliances, lights, and other devices.

1. Circuit: Wires that bring electricity to outlets, lights, and appliances. Each circuit can handle only a certain amount of electricity to stay safe.


2. Fuse and Circuit Breaker: Devices that stop electricity if there's too much current. A fuse needs replacing when it blows, while a circuit breaker can be reset.


3. Electrical Meter Reading: A device that shows how much electricity your home uses. For example, it might show you used 1000 kWh in a month.


4. Billing: Your electricity bill is based on how much electricity you use. If you use 1000 kWh and the cost is 50 Naira per kWh, your bill would be 50,000 Naira.
