How much amps take 12v 50w halogen lamb?
4.16 Amps
What size breaker for a 12 Volt 50 watt light?
50W@12V is 4.2 amps, so any breaker rated that or higher should work.
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.
How many watts will be consumed at 230v by a 12v x 50w lamp connected to a 230v supply via a transformer?
This question doesn't make sense as asked. In your question, you say 50w lamp. That means the lamp will draw 50 watts. However, the lamp can't be a 230v lamp and a 12v lamp. In either case, most lamps are rated by actual wattage, so look on the side of the box or on the stamp on each lamp.
How many amps does a 120v 50w halogen light bulb use?
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.

4.16 Amps
How many 12V 50W bulbs can you run on a 20-60VA transformer?
A 60VA transformer can run only one 50W bulb.
What size breaker for a 12 Volt 50 watt light?
50W@12V is 4.2 amps, so any breaker rated that or higher should work.
If a 12V device is dissipating 50W how much load resistance does the device represent?
P = V x I I = 50 / 12 I = 4.17 R = 50 / (4.17*4.17) = ~2.88

You are looking for a dimmer120vac-60hz 100-300w electronic transformer ip120v-60hz0.42a op eo1 01.5v-20-50w also jn1350 or e228739?
An electronic component of floor lamps sold by Home Depot that have a two-bulb 120v fixture on the top and a single bulb 12v fixture on a flexible arm. These may not be very reliable as the circuit board failed on mine in less than two years of light-duty service.
What is the lumen output for a 50W halogen?
Halogen lamps run hotter than conventional incandescents, and as a result of their hotter filaments, emit a whiter light with more of the light in the visible range, and less in the infrared. A typical 50W halogen emits between 800 and 950 lumens.In contrast, a fluorescent lamp produces more of its output as light instead of heat. Therefore a 13W compact fluorescent light emits the same number of lumens, while an 11-13W LED lamp emits the same 800 lumens (though this is rapidly improving)
How can calculate amps for 12v 50w halogen lamp?
The formula for current is Amps = Watts/Volts. The lamp itself would draw 4.16 amps. Since the voltage of the lamp is 12 volts there is a internal transformer involved in the fixture itself. It doesn't matter what the input (primary) voltage to the transformer is, so long as it meets the manufacturer's specification as to the proper voltage to operate the fixture.
How many watts solar panel do you ned to charge 12v battery?
You can charge it with ANY wattage 12 volt solar panel.The wattage of the panel will determine How Many Hours of sunlight you'll need to charge the 12 volt battery, so the next piece of information you need to consider is: what are you going to use that 12v battery for, and how quickly do you need it charged up?Here's the math-To figure out how many hours it will take to charge the battery, first figure out the output of the solar panel by dividing it's WATTS by it's Volts, which will give you it's output in AMPS. So. .a 15 watt panel DIVIDED by 12v = 1.25 ampsNext, read the Amp Hour rating on your 12v battery. If we use a 50 amp hour battery for this example. . .DIVIDE 50 amp hours [required to fully charge the battery] by the 1.25 amp output of the solar panel = 40 hours of direct sunlight to charge the battery. Then add another 10% of time to his number, so figure 44 hours.Some more examples:5watt/12vpanel=.42amp and 50amp hr/.42amp=119 +10% = 131 hours of sun30watt panel works out to 22hours. 50watt=13hrs 80watt=about 8 hrs.Of course all of these times are based a 50amp hour 12v battery.BTW, I'm no expert... i just found this equation online 5 mins ago because i was wondering the same thing myself. . Now could anyone tell me how figure out quickly my computer or light or whatever will drain that 12v battery??[Answer final question from above]To determine how quickly your battery will drain, let's assume that same 50AH battery. You wish to run 2-5W 12V lamps for about four hours each evening and use your small laptop for an hour which has a 50W draw at 18V, so about 80W at 12V. Your use will be 80W/12V=6.7AH + ((2*5W)/12V)*4 hours=3.2AH, or a total of about 10AH per evening. If you allow the battery to discharge to 50% before wanting to recharge it, you can run as described for about 3-3 1/2 evenings per week. If you concurrently have a 30W solar panel charging the battery for 4 hours per day, you will be keeping the battery fully charged it (you will be putting back 10AH per day). This allows for a couple of cloudy days.Hope this answers your question. Remember, watts/volts=amps. Multiply each load by the number of hours you need it to run to get ampere-hours. Add all these results together to determine the total draw on the battery.
How much heat does a light bulb make?
The electrical term Watts is a measure of heat. It is calculated by multiplying amps times volts, but it is still a measure of heat. A 50w light bulb made for 12 volts produces about the same amount of heat as a 50w light bulb made for 120 volts.
