What are stepdown transformers used for?
A step-down transformer accepts a given voltage on the primary winding (coil), and outputs a lower voltage on its secondary winding. A good example is a doorbell transformer you might buy for your home. It uses 120 volts from the house electrical system and steps it down to a safer 18 volts used to ring the doorbell. The voltage produced is a function of the 'turns-ratio' of the transformer. For example, if the transformer has 500 turns of wire in the primary, and 125 turns of wire in the secondary, we would say it has a turns ratio of 4:1 (pronounced "four-to-one"). If we feed 120 volts into the primary, the secondary would produce 30 volts. 120:30 = 4:1
How many coils are there in a transformer?
There are normally only one set of primary windings in a transformer. Some may have multiple windings though so that they can cover a wider range of input voltages.
Why induction transformer called rotating transformer?
Transformer has windings
How do you make a transformer on incredibots 2?

How can you find a real transformer?
Go to photograph if you see a transformer
What class is a transformer that converts 110 volts to 24 volts?
A transformer that reduces voltage is classed as a step down transformer.
What remains unchanged in transformer action?
In a standard transformer, the ratio of input volts to output volts remains constant.
How do you reduce 12 volts to 3.7 volts?
If the voltage is AC a transformer can be used.
How to increase 115 volts to 220 volts?
You need a step-up transformer.
How do you convert 7620 volts to 240 volts?
By using a step down transformer.
How many amps do you need to supply a 150kva transformer to get 118amps 480 volts?
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
How many volts does a mini connector have?
Depends on use,supply,AC,DC .Voltage,transformer ???
How do you make 16 volts at 12 volts car battery?
Step up transformer.
480 transformer to 120 ac current what is the kva on transfomer?
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.
How many volts per hour does a 75 kva transformer produce?
Volts per hour is an invalid statement. You may have meant Watts per Hour.
How many amps will a 0.25 kilo volt amp transformer at 120 volts put out?
2.083 amps
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
