That depends on the light and the amount of amperage the fixture/bulb is calling for. In a household you would find #14 or #12 gauge wire for lighting fixtures. In some commercial facilities you may find #10 guage wire being used, a good example of that would be parking lot fixtures.

A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.

Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.
A conductor used for grounding of the main service should be a single wire. The code book has a table that states the size of ground wire for different service panel amperages.

A lemon can power a light bulb because of the acid in it. The acid is used as a conductor and powers the lemon.

Wood can not let a light bulb light up because wood is a very poor conductor of electicity. A better conductor would be types of metals such as copper or gold, which is used in many electronics.

The most commonly used conductor of electricity is copper. For larger size service conductors the most commonly used conductor for electricity is aluminum. Aluminum service conductors are used to keep the overall cost of the project lower and are lighter to work with than copper wire.
The amount of current flowing through a conductor is governed by the amperage of the connected load. This is why there are different sizes of conductors. Each conductor size is only allowed a specific amount of amperage to flow through it. If the amperage load is higher that what the conductor is rated for then the next larger size conductor has to be used. The limiting of the amperage to specific size conductors keeps the conductor from heating beyond the conductors specifications, under full amperage conditions.

the polymer of ethyne or any other compound like propyne will be a conductor because it will have resonance because of alternating double bonds ....these plastics are used to make light batteries,light wires ,etc these are very light and have conductivity comparable to metals..........abhishek
The equivalent mm2 cross-sectional area of a 5.26 mm2 conductor is a # 10 AWG conductor. A # 10 AWG conductor size is protected by a 30 amp fuse.

In most home wiring circuits, the black wire is used to power a light bulb. The other wire is white and is called the neutral conductor.
