which has more resistance 100 watt bulb or 60 watt bulb?

In short, the 60 watt bulb has more resistance.

Power can be calculated using the following formula: P = (V^2)/R The power rating for a light bulb is measured using a 120 Volt source. Since the voltage will be the same for both light bulbs, using the formula, the bulb with the lowest resistance would have the greatest power.

Which has more resistance a 100 Watt light bulb or a 75 Watt light bulb?

A 75 watt light bulb has more resistance because less current is going through which causes less light.

Which bulb has more resistance a 50 watt or a 100 watt?

Assuming they both run at the same voltage, the one with less resistance will draw more current and more power.

Does a 100 watt bulb put out more light than a 25 watt bulb?

If both are incandescent bulbs, a 100 watt bulb puts out more light than a 25 watt bulb.

Which glows more brightly- a 100-W bulb or a 75-W bulb?

The difference between the power of a 100 watt bulb and a 75 watt bulb is 25 watts. A 100 watt bulb will burn about 25 percent brighter than a 75 watt bulb.

Which bulb uses more electricity40 watts100 watts or 120 watt?

The higher the wattage the more you pay for power. So it costs more to operate a 120 watt bulb than it does a 100 or 40 watt bulb.

100 watts

Which consumes more electricity a halogen bulb or an incandescent bulb?

How much electricity is consumed depends only on the power Wattage of the light bulb. No matter what types of bulbs they are, a 100 Watt bulb will always consume more electricity than a 60 Watt bulb. The type of bulb makes no difference to how much electricity is consumed but does make a big difference to the amount of light that is produced. In general: * a 100 Watt halogen bulb will produce more light than a 100 Watt normal incandescent light bulb; * a 20 Watt compact fluorescent light (CFL) bulb will produce about the same amount of light as a 100 Watt incandescent light bulb.

How much more money will it cost if you use 100 watt bulb then a 60 watt bulb?

Almost twice as much as 100 is almost twice 60.

Why is 60 watts written on the bulb?

It is probably a 60 watt bulb (believe it or not). Bulbs are rated in watts. A 100 watt bulb is brighter and consumes more power than a 60 watt bulb

Why is 100 watts lamp bulb brighter than a 60 watts lamp bulb?

Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.

The problems of electricity two light bulbs of 100 watt and one 60 watt both operation in a 220V circuit Which bulb has the higher resistance and which bulb carries the greater current?

A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.

Does a 60 watt halogen give the same brightness as a 100 watt normal bulb?

Not quite as much, about the same as an 80-watt normal bulb. But a 20-watt energy-saving bulb is as bright as a 100 watt normal bulb.

100 watt bulb equal how many volt?

A 100 watt bulb equals zero volts.

Why is a 100 watt light bulb brighter than a 40 watt light bulb?

Because more energy goes through it, you pay more and you get more result.AnswerA 100-W lamp has a lower operating resistance than a 40-W lamp. Since power is equal to the voltage squared divided by the resistance, for a given voltage the power will be higher and its operating temperature (therefore brightness) will be higher.

What is the difference between a 60watt light bulb and a 100 watt light bulb?

The 60 watt bulb will consume less energy and not be as bright as a 100 watt bulb. Most bulb sockets will specify a recommended bulb rating.
