To function, every circuit shown in the video requires four essential parts:

A device that consumes energy, such as a light bulb or a small motor. g7236.mp4

Wires (often copper) that provide a path for the current to flow. To function, every circuit shown in the video

Usually a battery or DC power supply that provides the voltage (electrical pressure). g7236.mp4

Verify that all wires have intact plastic coating to avoid exposed live parts.

): Measured in Amps; the actual flow of electrons through the wire. Resistance (

Components are connected end-to-end. If one component fails (like a bulb burning out), the entire circuit breaks and all lights go out.
