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.

easy. The wire is a resistor. Hence, voltage is lost when the current flow through.

∙ 13y agoyes. there is more resistance in a longer wire.

∙ 15y agoThe decreasing the length of the wire increases the brightness of the bulb for a given voltage.

How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
How thickness of wire affects brightness of bulb?
Considering that everything else is equal, ie. glass, incoming wire. If you are talking only about the filament wire that is attached between the Two poles inside the bulb, the answer is friction. The thicker the wire the less resistance it will have and will allow more electricity to pass without creating friction, the friction is what causes the wire to heat up and glow.
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.
Why does the resistance of a filament bulb depend on the current in the bulb?
The resistance of a piece of wire changes with temperature. In a filament bulb the wire is heated to about 3000 degrees C so a large change in resistance can be expected. A 240 v 105 w halogen bulb has a cold resistance of 35 ohms, but when running its resistance is 549 ohms.
The thin wire in a bulb is called what?
filament

What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.

Is a bulb dimmer when the wire is longer?
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.
When you add more batteries to a circuit what happens to the bulb brightness?
if you put too many batteries in the socket, the bulb will blow out because there would be too much energy passing through the circuit. If you put too little amount of batteries in, the brightness will be low, and will probably run out, because of the little amount of energy passing through the circuit the more batteries, the brighter the bulb
How will a single burned-out bulb affect the strings of lights if each light is attached to its own wire?
If by "its own wire" you mean they are connected in parallel, then one bulb won't affect the others.
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 would affect the brightness of a lamp?
Voltage applied (voltage at source, resistance of wire and conections etc), ground resistance, designed brightness of element in comparison to the applied voltage
Does the length of a wire affect the strength of an electromagnet?
longer= stronger
What are factors that affect resistance of electricity?
Temperature, thickness, length and type of wire.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
No, only the resistance of the filament counts (normally marked as "wattage" on the bulb).
What doesn't affect the resistance of a uniform circular copper wire?
Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire
