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

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

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.


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.


Does a high watt bulb give more energy than a low watt bulb?

More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.More watts means it uses more energy per second (watt is a unit of power).

Do fans or lights use more energy?

energy is energy It does not matter what you are using the energy for, it matters how much energy you are using A 200 watt light bulb uses more energy than a 100 watt light bulb A 200 watt motor uses more energy than a 100 watt light bulb A 200 watt heater uses more energy than a 100 watt light bulb



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.


A 5-Watt and 50-Watt bulb are connected in series which bulb will glow brightly?

The 5 watt bulb will glow brightly. The reason has to do with resistance. The higher watt bulb will have the lowest resistance. When you put the two in series, low resistance causes the lowest voltage drop. Higher resistance causes higher voltage drop, therefore the lowest wattage (highest resistance) bulb will have more voltage across it than the other bulb, and will glow brighter.


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.


Which one produces more light a 60 watt bulb or two 30 watt bulbs?

No way to know. Light is not proportional to watts. You could have a "30-watt bulb" that produces 50 times more light than an inefficient 60-watt bulb, depending upon what technology is used in each bulb.


Why is a higher watt light bulb brighter than a lower watt one?

The filaments in the bulb are larger and draw more electricity. The bulbs also get hotter if you will notice. The filament in a higher wattage bulb is actually smaller than a lower wattage bulb. The smaller filament has less resistance which allows for more current to flow. More current, more heat, more light.


A 60-watt 120 volt lamp requires morecurrrent than a 40 watt 120 volt lamp?

Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.


Is a 10 watt bulb the same as a normAl 40 watt bulb?

Electrically, a 10-watt bulb uses 75% less energy than a 40-watt bulb. For the same circuit voltage, let's say 120v, a 10-watt bulb would only draw 0.083 amperes, compared to 0.33 A for a 40-watt bulb. Light-output-wise, they may not have the same ratio of light output. If a 40-watt lightbulb provides 400 lumens of light, a 10-watt lightbulb that is more energy-efficient than the 40-watt bulb may produce more than 100 lumens which is greater than 1/4 of the light output of the 40-watt bulb. A 10-watt bulb that is less energy-efficient than the same 40-watt bulb would produce less than 100 lumens of light.


Do 54 watt light bulbs burn hotter than 40 watt bulbs?

Yes because the more watts a light bulb means it lets out stronger light, but with more light it creates more heat, so the more watts in a light bulb = more heat and stronger light


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.


Which type of bulb is more efficient incandescent or fluorescent?

A typical 20-watt compact fluorescent light bulb can produce about as much light as a 100-watt incandescent light bulb. There is an 80 per cent improvement in efficiency.


Does a 25 watt light bulb draw more current than a 60 watt light bulb?

No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.



Does a 35 watt halogen bulb give off as much light as a 75 watt incandescent bulb?

No, halogens produce only about 30% more light than incandescents, so a 35 watt halogen is equivalent brightness to a 45 watt incandescent.


Can you use a higher watt energy saver bulb in a lower watt light fixture?

Yes, because the "higher" watt energy saver bulb (cfl) is actually a lower watt bulb than a standard (incandescent). Always look at the actual watts, not the 'light equivalent watts'. 11 watt low energy tube = 60 watts of old-fashioned light. More light, less heat!


How is the brightness of a light bulb determined?

Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.


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

Becouse there flows more energy trough it?


How come a 60 watt light bulb has a higer temperature than a 40 watt light bulb?

The electric power measured in watts is used to heat a filament in the light bulb (which glows because it is very hot). More energy gives more heat. It's very simple.


Why does a 100W light bulb cost more than a 1200-W hair dryer does?

A 100 watt light bulb does not cost more that a 1200 watt hair dryer. The average price of a light bulb is about 90 cents whereas a hair dryer can range up to 20 dollars.


Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?

Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.
