What else can I help you with?
An electric bulb is rated 220v and 100wWhen it is operated on 110v the power consumed will be what?
When the electric bulb is operated at 110V instead of its rated 220V, the power consumed will be reduced to 25W. This is because power is proportional to the square of the voltage, so halving the voltage will quarter the power consumed (P = V^2/R, where R is constant for the bulb).
Is there is a magnet in a torch?
No, a torch does not typically contain a magnet. The main components of a torch are a battery, light bulb or LED, and a casing to hold everything together.
When a light bulb is rated at 60 watts it means it?
When a light bulb is rated at 60 watts, it means that it consumes 60 watts of electrical power when it is turned on. This power consumption determines the brightness of the bulb and is used to measure its energy usage.
Which makes the conducting link between the cell and the bulb in the torch?
The conducting link between the cell and the bulb in a torch is the wires inside the circuit. When the switch is turned on, the circuit is completed, allowing the electrical current to flow from the cell through the wires and to the bulb, causing it to light up.
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
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
Which is more powerful a torch bulb or a mains filament bulb?
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.

Where is energy stored in a torch?
Energy in a torch is stored primarily in its battery or power source. When you switch the torch on, the battery converts stored chemical energy into electrical energy, which powers the light bulb or LED to produce light.
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.
The power of a light bulb is measuerd in?
Light bulbs are rated in watts
Why is there glass on the end of a torch?
It is there to protect the bulb.
What conductors are there in a torch?
The conductors in a torch are typically made from metals such as copper or aluminum. These metals have high conductivity, allowing the electrical current to flow efficiently through the circuit and power the light bulb.
How do workers change the light bulb in the torch on the statue of liberty?
Walk to the torch with a latter and change
