There's not enough information in the question to provide a definite answer. It is like asking "How long does it take to get from point A to point B?" The answer depends on other factors i.e. How far is it and what is your average speed?

How much voltage is needed for a 100 watt light bulb? The answer depends on the design of the bulb. A 12 volt 100 watt bulb requires 12 volts to function at a power level of 100 watts. Likewise, a 120 volt 100 watt bulb requires 120 volts to function at 100 watts. As far as I know, that's about all the answer there is.

Obviously this person is talking about the 100watt light bulbs that you would find in any grocery store across the country. Those require 110 volts. That's what comes out of your wall socket. If you were to travel to Europe you would need a different bulb because they run 220volt electrical lines to their outlets. We measure the electricity running into our homes(or potential energy) by volts and amps. Watts are a measure energy used.

1watt = 1volt x 1amp.

A light bulb is not only rated in watts, it is rated in voltage also. The lamp has to be operated on the voltage specified by the manufacturer of the light bulb. Too high a voltage and the lamp life will be shortened. Too low a voltage and you will not obtain the full wattage of the lamp.

What ever the voltage that is stated on the lamp is the voltage that should be applied to it.

The amount of power needed to light up a bulb is measured in watts and is marked on the bulb, along with the correct operating voltage. For example 240 v 20 watts.

The bulb need the correct voltage to operate. Your bulb would light if it is a 1.5 volt light. So the voltage of the supply and the light must be matched. Too little voltage won't light the light, too much will light it too much and blow it up.

You answer is on the light bulb. Watts is the same as power.

User Avatar

50 Answer 2 Depends on what voltage the bulb was designed for. A 12 volt bulb in a car headlamp needs 12 volts.

The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.

the actual filament itself in a light bulb has the most resistance,this is why it glows and produces light,the rest of the bulb is sufficiently engineered to carry the voltage and current applied to it without producing too much heat.

it varys from light bulb to light bulb.

Assuming the bulb is connected to the proper voltage, all 60 watts of energy are "lost" in a light bulb, mostly converted to heat and a small amount as visible light. If you meant how much energy is used to create a 60 watt bulb, that's completely different.

User Avatar

The result is depend on the capacity and the type of the bulb, if the bulb is made of the material which have the high melting point and it have the high resistance then the bulb will light and if the bulb can't afford the voltage means the resistance of is not to much high or the area of the filament is thin then the bulb will light for 1 or 2 sec after that the filament will break and the bulb will not be able to light again.

The current is irrelevant. What matters is the voltage. For a lamp to operate at its rated power, it must be subject to its rated voltage (that's why both the rated power in watts, and the rated voltage in volts, is printed on the lamp).To determine what current this combination of power and voltage draws from the supply, you simply divide the rated power by the rated voltage.

User Avatar

The circuit voltage or the resistance of the individual bulb is needed to answer this question. Divide the total power (400 W) by the supply voltage.

User Avatar

100 Watts means 100 Joules/second. The voltage is not required for this calculation.

User Avatar

Actually the range of the voltage required for the bulb is depends on type of the bulb. Hence the range is mentioned on the pack of the light. It may be 30v, 60v,120v. In order to avoid voltage fluctuations place a adapter to the bulb. Vocca adapters are available in the market. They can reduce the voltage fluctuations. And also vocca adapters are voice activated adapters.

Only if the voltage is correct. If you connect a 110V lamp to a 12 V battery, you won't see much. When you connect a 1,5V lamp to a 12V battery, it will burn out.

Some small voltage above 0.

The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.

User Avatar

100 watts. your voltage and amps are what detemines how many watts you can put on the circuit.

User Avatar

LEDs don't operate on voltage, they operate on current. connecting them to a voltage source will destroy them.

a single incandescent light bulb is around 1.49$

No. The Sun is much hotter than a light bulb is.
