In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.
Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.

Is circuit part of a light bulb?
A light bulb can be part of a circuit.
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
What does light bulb do in a circuit?
It completes the circuit!!
What would happen if you didn't have a light bulb for a circuit?
it would be ok in a circuit which didn't need a light bulb.
What job does a bulb do in a circuit?
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
What happens if you unscrew a light bulb in a series circuit?
The circuit will have the flow of electricity interrupted.
How do you make a battery light a light bulb?
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
A type of circuit that allows the light bulb to turn on?
a closed circuit
In which circuit will the light bulb be the brightest?
the circuit which has the maximum power output
Why the bulb is not lighting when one wire or terminal is not connected?
When one wire or terminal is not connected to a light bulb, it is not possible for electricity to complete the circuit. When a circuit is not completed, the bulb will not light. An off switch, for example, breaks the circuit.
