It would be pretty much undefined, since the filament of the halogen bulb would fail immediately then there would be an open circuit with no current draw.
<<>>
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 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 amps does 500 watt halogen pull?
At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
How do you calculate multiplying factor from ct ratio?
The CT standard output is 5 amps at the rated input amps. The CT will have a marking like 400:5, 100:5, or similar, where the bigger number is the input current that will cause 5 amps to flow in the CT secondary. Divide the span by 5 to get the multiplier. For instance: CT - 400:5 400 / 5 = 80 So, if you measure, say, 3 amps from the CT, the primary current is: 3 * 80 = 240 A
What fuse do you need to run a 200 watt bulb with 230V?
The formula you are looking for is Amps = Watts divided by Volts. Once you find the amperage you can decide as to the size of a fuse you should use. Remember that fusing protects the conductors of the circuit and not the load of the circuit. A #14 wire is rated at 15 amps and can legally be loaded only to 12 amps.
What size fuse should be used for 2 amp power supply?
If the 2 amps is the output amperage of the power supply, the maximum that should be drawn from the unit is 2 amps. The load amperage that is connected to the power supply should govern the amperage of the fuse used. There is not much range there, the fusing could go from .25 to 2 amps. If the input amperage is 2 amps then the input and output voltage of the power supply should be stated.
How many amps is 2 hp at 230V 3 phase?
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
How much amps take 12v 50w halogen lamb?
To calculate the current, you can use the formula: current (in amps) = power (in watts) / voltage (in volts). So, for a 50W halogen lamp operating at 12V, the current draw would be approximately 4.17 amps (50W / 12V = 4.17A).
How many amps does a 1.5 hp 230v 3 phase motor draw?
For a 1.5 hp 230v 3 phase motor, you can calculate the amperage using the formula: Amps = (HP x 746) / (Volts x Efficiency x Power Factor x √3). Assuming an efficiency of 0.85 and a power factor of 0.8, the amperage draw would be approximately 4.3 Amps.
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 amps will an 12000 btu air conditioner pull?
at 230v it will use 5 to 6 amps
How many amps is 32 watts?
To calculate the amperage, you need to know the voltage. The formula to calculate amperage is: Amps = Watts / Volts. For example, if the voltage is 120V, then the amperage for 32 watts would be 0.27A.
How many amps are in 1600 watts?
To calculate the amperage, you need to know the voltage of the circuit as well. You can use the formula: Amps = Watts / Volts. If the voltage is 120V, then 1600 watts / 120 volts = 13.33 amps.
What is the current rating using a 230v supply motors power is 500w?
3 amps
What is the compressor amperage of a 3-ton system operating on 230v?
17amps
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 is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
How do you work out amps of current from 230V connected to 534 ohm resister?
you divide the volts by the ohms
