Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
Explain how you can test whether something is an insulator or conductor?
You can test if something is an insulator or conductor by connecting a circuit with a power source and a light bulb. If the material allows the light bulb to turn on, it is a conductor. If the light bulb does not turn on, it is an insulator.
Will a light bulb turn on or off when it is touched by a conductor to complete the circuit?
If a light bulb is touched by a conductor to complete the circuit, it will turn on if the circuit is closed and working properly. The conductor helps to create a path for the electricity to flow from the power source to the light bulb, allowing it to illuminate.
How can you make a circuit to find out if an object is an insulator or a conductor?
You can create a simple circuit with a battery, a light bulb, and wires. Connect the wires to the battery and light bulb, then touch the ends of the wires to the object in question. If the light bulb lights up, the object is a conductor as it allows the flow of electricity. If the light bulb does not light up, the object is an insulator as it does not allow the flow of electricity.
Will bulb glow in milk?
No, a light bulb will not glow if placed in milk. Milk is not a conductor of electricity, so it will not allow the flow of current needed to power the light bulb.
