An electric bulb is rated 220v and 100wWhen it is operated on 110v the power consumed will be what?
25w
What is the power rating for a light bulb in one hour?
Light bulbs have various ratings. They are rated in Watts.
What is the power of a light bulb?
Every person has a different power of light bulb. In my room, I have a 7.5 and a whole bunch of 60s. The number of watts you choose for your light bulb depends on how bright you want your light to be. The higher the number, the brighter it is.
How may watts is 400 lumens?
Bulb brightness in LumensA 100 watt Bulb is rated at approximately 1700 lumensA 60 watt incandescent bulb is rated at approximately 800 lumensA 40 watt bulb is rated at approximately 400 lumensA 25 watt bulb is rated at approximately 180 lumensA 4 watt night light bulb is rated at approximately 20 lumens
Will a higher wattage hps bulb work in a ballast that came with a lower wattage bulb?
A higher wattage HPS bulb may work with a ballast that is rated for a lower wattage bulb , but may appear to be dim and will not produce the rated light output. It is best to match ballast and bulb accordingly.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament
What thing besides a torch can you make with one small bulb and three batteries?
you can make a torch bulb
How does a bulb glow when a torch is switched on?
If your torch has an incandescent bulb in it, the resistance of the wire in the bulb generates enough heat that light is created. If your torch has an LED bulb, the PN junction in the diode creates light when the diode is forward-biased.
How does a torch work-circuit'?
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

What is the job of the cells and wires and bulb and switch in a torch?
The job of a bulb is to give off heat and light energy
The power of a light bulb is measuerd in?
Light bulbs are rated in watts
What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
What is the general resistance of a tungsten filament?
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
Why is there glass on the end of a torch?
It is there to protect the bulb.
Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
How do workers change the light bulb in the torch on the statue of liberty?
