The resistance of a wire is proportional to its length so increasing the length would increase the resistance of the wire. The higher the resistance of a wire the lower the voltage will be across the bulb so theoretically, the bulb will be somewhat dimmer.
However, the resistance of a wire is extremely low compared to that of the light bulb. Electrical wiring is designed and installed so that the wire resistance is insignificant compared to the resistance of the load, such as the bulb. In a well planned wiring system, it will be impossible to see any difference in brightness in bulbs regardless of their location in the electrical circuit. In most cases, it will require very sensitive measuring equipment to detect any difference at all.

What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.
What will happen if the tiny wire in a light bulb breaks?
The filament , once broken , will no longer generate any light because the connection is now broken and no longer conducting any electricity .
Describe how a meter would be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
Does the length of the wire affect the brightness of the bulb?
Wire has a certain amount of resistance. As electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp. So, the longer the wire, the less voltage the lamp gets, and the dimmer it will be.
Which wire would make the bulb dimmer copper or plastic or gold?
plastic as its the worst electrical conductor
What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.
How bright is the bulb when a shorter wire is used?
Depending on the length of the wire difference between the shot and long wire, in technical fact the bulb would be brighter if a shorter wire was used, but not that much brighter. Energy is used up as it travels along wires.
What happens to a series circuit if a longer wire is used?
Resistance is increased so the light will be dimmer.
How do you use the word dimmer in a sentence?
A 40 watt bulb is dimmer than a 100 watt bulb.
What wire does the illumination dimmer wire connect to?
12v switched source. such as headlight switch or dimmer on the dash.
Do dimmer switches reduce bulb life?
Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
How do you know whether to get 120 volt or 130 volt light bulb?
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
What is the type of lamp uses with dimmer switch?
You cannot use most fluorescent lights with a dimmer. Just about any incandescent bulb WILL work with a dimmer. Occasionally, when a halogen bulb burns out, it will destroy a dimmer switch but halogen bulbs are considered incandescent and other than that little problem they work well with a dimmer.
Does a burned out bulb use electricity?
Assuming it's a filament (incandescent) bulb, no. When a bulb burns out, the tiny wire in the bulb is broken, and the electricity can no longer pass through the bulb. It's the same as if it was switched off.
What is a dimmer?
A dimmer reduces the voltage to a light so that the current is reduced, which causes the bulb to have a reduced lumen output.
