Homonym: circuit (Race)
A circuit is a closed loop that allows electricity to flow. It consists of various components, such as wires, resistors, and power sources like batteries. When the circuit is complete, electrical current can travel through it, powering devices like light bulbs or motors.
Circuits can be simple, like a flashlight, or complex, like those found in computers. They can be classified into two main types: series circuits, where components are connected one after another, and parallel circuits, where components are connected across common points. Each type has different properties and uses in electronics.
