Why it is possible to light the bulb even though only one wire is used?

A complete electrical circuit is formed even with just one wire because the wire provides a path for the flow of electrons from the power source to the light bulb and back. This flow of electrons allows the bulb to light up. In this scenario, the bulb is acting as a resistor completing the circuit.

What is the wire in a light bulb?

The wire in a light bulb is typically made of tungsten. When an electric current passes through the wire, it heats up and emits light, creating illumination in the bulb. The tungsten wire has a high melting point, allowing it to withstand the heat generated during operation.


How does the amount of magents and wire affect the brightness of a light bulb?

The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
