The w means watt. It is a unit of measurement that quantifies the energy given off by the globe when it is switched on.

When compared in a given time interval with other light bulbs connected to a 120 V circuit a 60 W lightbulb?

A 60 W light bulb consumes more power (produces more light) than a 40 W light bulb in a given time interval when both are connected to a 120 V circuit. This is because power is directly proportional to the wattage rating of the light bulb.


Why does it require more work to light a 100 W light blub than it does to light a 150 W light blub?

It doesn't, and we can't imagine where you got that idea. A light bulb that's operating at 150W is dissipating 50% more energy (work) than a bulb operating at 100W. Could it be that someone had you on a bicycle, pedaling furiously to turn a generator and light some light bulbs ? If so, that's such an uncontrolled experiment, with so many variables involved, that you really can't draw any conclusions from what you saw, except for the fact that it takes work to generate electrical energy.


How many lumen in a 60 w light bulb?

A 60-watt incandescent light bulb typically produces around 800-900 lumens. However, this can vary depending on the specific type and brand of the bulb. LED and CFL bulbs can provide the same amount of light output (lumens) as a 60-watt incandescent bulb while consuming less energy.


Coal has about 30E6 J of energy per kg but a power plant can only use 30 of this energy to make electricity (i.e. it is 30 efficient). How many kilograms of coal have to be burned to light a 100 W lig?

To light a 100 W light bulb, you need to generate 100 W of power. If the power plant is 30% efficient, you need 100/0.30 = 333.33 W of input power. Since coal has 30E6 J/kg of energy, you would need 333.33 W/30E6 J/kg = 0.0111 kg of coal to light the 100 W bulb.


Why is a 100 watt bulb brighter than a 25 watt bulb?

A 100 watt bulb is brighter than a 25 watt bulb because it consumes more electrical power, which in turn generates more light output. The higher wattage allows the bulb to emit more brightness and illuminate a larger area.

A 40W bulb or a 60W bulb will glow more brighter if connected in series?

Oh, dude, let me break it down for you. If you connect a 40W bulb and a 60W bulb in series, the 60W bulb will glow brighter because it has a higher wattage rating. It's like having a race between a tortoise and a hare - the hare (60W bulb) is gonna shine brighter than the tortoise (40W bulb). So, yeah, the 60W bulb takes the spotlight in this series connection scenario.


What does it mean by writing V and W in a bulb?

V on a light bulb means volts. W means watts.


On a Volvo 850 Wagon what does the indicator light with the light bulb w an exclamation point mean?

A typical light bulb in your house is rated 60 W which means that the bulb dissipates 60 W when connected to a DC voltage of 110 V What is the currrent?

P=VI 60W = 110V x I I=0.54* A Hopefully in your house you are connected to 110 VAC and not DC. Same answer as above applies.


What is equal to 60 watt in CFL?

If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.


How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?

What one is brighter a 60 watt light bulb or a 100 watt light bulb?

If the two bulbs use the same technology the 100 w bulb is 10/6 times brighter than the 60 w. Incandescent bulbs give about 10-12 lumens per watt Halgogen gives about 15-18 lumens per watt CFL (low-energy) gives about 50 lumens per watt.

How many lumens in a 60 watt incandescent bulb?

That depends a LOT on the technology used - some technologies are much more efficient than other (converting a higher percentage of the power used into visible light).


Two lamps A and B are rated 60W 220V and 100W 220V respectively so why does the answer say that when connected in parallal bulb A is brighter?

In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one. The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.


The power delivered to the light bulb is 23.1 W. What are the two possible resistances of the light bulb?

A: HARD TO SAY because a bulb has different resistance as it warms up


What is the recommended wattage for a 25 w light bulb in this fixture?

The recommended wattage for a 25-watt light bulb in this fixture is 25 watts.
