Which is more efficient and why 5- 50w 120v halogen lights or 5- 50w 12v halogen lights run on a transformer?
In both cases, you're operating five 50-watt lights, so you're getting the benefit of
250 watts of power. You haven't said how much power you have to feed to them,
or which halogen light is more efficient, so we can't calculate any efficiency.
Just on general principles, the only difference in the two setups that we're sure of
is the transformer, and there's always a bit of loss in a transformer, so there's a
reason to speculate that the second situation is a bit less efficient. But aside from
that, we're woefully short of electrical information on which to base an answer.
By the way ... There's also no reason to expect that lights running on higher or
lower voltage are any more or less efficient than those designed for the opposite
conditions.

How do you calculate voltage ratio of Transformer?
Count the turns ratio of the windings. The voltage ratio is equal to the turns ratio. The current ratio is equal to the inverse of the turns ratio. For instance, a power transformer with a 10:1 turn ratio (primary to secondary) running on 120V will produce 12V. If it consumes 1 ampere from the input, it will provide 10 amperes to the output.
What is the standard power of apc 1500?
The APC 1500 has a standard power of 865 watts/1500 VA. The APC 1500 has an output of 120V and an output of 120v. The specifics of the model can be found on the official website.
What is 2 wire plus ground 240V?
With one interpretation of this question, the answer would be two 120V wires and a ground.
What is the line voltage between two lines?
the voltage between 1 line & phase =120v The voltage between 2 line =240
What does 240 mean?
240 refers to the voltage used in an electrical system. The US uses 120V/240V, while the UK uses just 240V.
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 kind of transformer for going from 120v to 220v?
This type of a transformer is known as a step up transformer.
What is the ratio of a potential transformer from 4160V to 120V?
4160/120 = 34.666666 to 1
Why does my 120v 24v reduce to 28v. when you connect it to your boiler it blows out the transformer. is a problem with the transformer or the panel?
Please go to discuss question page.
Can 120V appliance work with 220V?
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No, you cannot directly run a neon sign designed for 120V power on a 240V power outlet in Australia. The different voltage and frequency could damage the sign or be a safety hazard. You would need a voltage converter or transformer to safely operate the neon sign on the higher voltage.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
How do you use 205V equipment on 120V?
You can use a transformer or voltage converter to step up the voltage from 120V to 205V for your equipment. Make sure to select a transformer that can handle the wattage and current requirements of your equipment to avoid damaging it.
What is the output of the control transformer?
Depends on what the voltage is being stepped down in that particular control transformer. Control transformers usually step down a voltage of 480/208v to 120V. The 120Volts can now be used in safer manner to "control" start/stop buttons, and other components that are only built to run on 120V
How do you get 480v circuit from 120v?
To get 480V from 120V, you can use a transformer. A transformer with a turns ratio of 4:1 will step up the voltage from 120V to 480V. Make sure to follow proper safety protocols and consult an electrician if needed.
How do you convert 480v to 120v?
To convert 480V to 120V, you can use a transformer. You would need a step-down transformer that can reduce the voltage from 480V to 120V. The transformer will have a primary winding designed for connection to the 480V source and a secondary winding for the 120V output.
Is there any way to convert car led strips for wall outlets?
Probably a transformer that converts voltage from 120v AC to 12v DC. Commonly found at Radio Shack or an electronics store. Depending upon how much the lights draw for current, you have to find a transformer that will supply that current. Such as .5 amp or 2 amps or as much as 5 amps-----.
