At what voltage? Until you tell me the voltage I can't give you an answer.

To find out Amps you need to divide the Watts by the Volts.

At 120V you have 0.4 amps. At 12V you have 4 amps.

You could do so, but from safety perspectives it's better not to do so. A 50W bulb will draw a higher current from the grid, which the 45W fixture is not designed for, so it might break down.

The equation that you are looking for is Amps = Watts/Volts.

How much current does a 75 watt light bulb draw from a 120v wall outlet?

It's 75/120 and the answer is in amps.


How many amps does 65 watt light bulb draw?

A 65-watt light bulb operating at 120 volts draws approximately 0.54 amps of current. You can calculate this by dividing the wattage (65 watts) by the voltage (120 volts) to get the amperage.


How many amps would a 150 watt bulb draw in a 120v circuit?

1 amp


Does 1000va equal 10 amps?

No, 1000VA does not necessarily equal 10 amps. The relationship between VA (volt-amperes) and amps depends on the power factor of the load. For a purely resistive load (like an incandescent light bulb), 1000VA at 120V would be equivalent to approximately 8.3 amps.


Can a light bulb work on a DC voltage?

It can, but if you're wanting to run a 120v light bulb on DC, you'll need 120v DC to get the rated output. That's a lot of batteries. It's easier, and more sensible, to find a DC rated light bulb, such as an RV bulb.


How do you determine the amps for a halogen lamp?

To determine the amps for a halogen lamp, divide the wattage of the lamp by the voltage it operates on. The formula is: Amps = Watts / Volts. This will give you the amperage required for the halogen lamp.


What size is a halogen bulb?

Halogen light bulbs are made in a variety of sizes to meet different needs.


What is more efficient a 120V 13W fluorescent bulb or a 12V 50W halogen bulb?

Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.


What gas is a halogen filled with?

Halogen is a gas, so your question doesn't make much sense. If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
