When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.

The 3 conditions that have to be satisified for an electric circuit to make a bulb glow are:

2.The connecting wire should be made of conducting material like Copper.
3. the electric circuit should have a power source like battery
