Circuit diagram when two lamps are connected in parallel
When two lamps are connected in parallel, if one terminal is connected to two wires, two branches will be formed, and there will be no circuit failure. When drawing a circuit diagram, you should clearly mark two branches, one is the light bulb and the other is the other.
Circuit diagram of parallel connection of light bulb and wire
If a light bulb is connected in parallel with a wire, the current will flow directly to the wire because the resistance of the wire is very small. You can stretch the wire into the light bulb imaginatively, as if another wire didn't touch the post at all and was directly connected to the first wire. In this way, does it feel much easier to understand?
