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.
What else can I help you with?
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 kind of transformer for going from 120v to 220v?
This type of a transformer is known as a step up transformer.
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 are the best under cabinet lighting options available in 120v?
Some of the best under cabinet lighting options available in 120v include LED strip lights, puck lights, and linear fixtures. These options provide bright and energy-efficient lighting for your kitchen or workspace.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.
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 get 120V from 380V 3 phase?
Yes, you can obtain 120V from a 380V three-phase system using a transformer. By utilizing a step-down transformer designed to convert 380V to 120V, you can safely provide the desired voltage for single-phase loads. Additionally, you can also achieve 120V by using a phase-to-phase connection in a three-phase system, depending on the system configuration. However, it’s crucial to ensure that the transformer and wiring are properly rated for the application to ensure safety and efficiency.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
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.
Can you get 120v single phase from 440 3 phase?
Yes, you can obtain 120V single-phase power from a 440V three-phase system using a transformer. By using a step-down transformer that reduces the voltage from 440V to 120V, you can safely access single-phase power. It's important to ensure that the transformer is correctly rated for the load and that all safety regulations are followed during installation. Always consult with a qualified electrician for any electrical work.
