It depends on the load. A good transformer has over 90% (some as high as 99%) efficiency. So the power drawn by it is a function of the power in the load, plus a small amount due to losses in the transformer.

What type of transfomer increases the voltage produced by the source?
step- up transformer
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
What is the differences between a step-down transformer and a step-up transformer?
the main function of transformer is to change the magnitude of Voltage. difference between step up and step down is step up will change the input voltage into a larger magnitude of output while step down is vice versa
How do you figure out maximum current of a 240V transformer circuit?
Your best bet is to go to Acme Transformer on the web and once you are on their web page select how do I rate a transformer, they have everything single phase 3 phase step up step down.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.

A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?
Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.
Where can one find instructions on how to draw Manga eyes?

How do you produce a step-up transformer in an ordinary transformer?
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
What is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.
Step up transformer is used to increase the?
A step up transformer is used to step up an AC voltage
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
