Never connect the positive and negative terminals of a battery directly without a load, as this can cause overheating or fire.
Wires (often copper) that provide a path for the current to flow. g7236.mp4
Usually a battery or DC power supply that provides the voltage (electrical pressure). Never connect the positive and negative terminals of
): Measured in Amps; the actual flow of electrons through the wire. Resistance ( g7236.mp4
Components are connected end-to-end. If one component fails (like a bulb burning out), the entire circuit breaks and all lights go out.
): Measured in Ohms; how much the material resists the flow of electricity.
