Understanding Electrical Circuits

As I investigate the reason behind flickering lights when the coffee maker is on, it’s important to understand the basics of electrical circuits.

An electrical circuit is a path that allows electricity to flow. It consists of a power source, wires or conductors, and a load, which is the device that uses electricity. In a home, the power source is typically a transformer that steps down the voltage from the utility company’s power lines to a lower, safer level for household use.

The wires or conductors carry the electricity from the power source to the load. In a typical home circuit, there are two wires: a hot wire that carries the electricity and a neutral wire that completes the circuit. The hot wire is usually black or red, while the neutral wire is white or gray.

When a load is turned on, it draws current from the circuit, which causes a voltage drop. This drop in voltage can affect other devices on the same circuit, causing them to flicker or dim.

It’s important to note that circuits are designed to handle a certain amount of current, known as the amperage rating. If a load draws more current than the circuit is designed to handle, it can cause the circuit breaker to trip or the wiring to overheat, which can be a fire hazard.

In summary, understanding electrical circuits is crucial in identifying the cause of flickering lights when the coffee maker is on. By understanding the flow of electricity and the components of a circuit, it’s possible to troubleshoot and fix the issue safely and effectively.
