What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What value for a transformer determines the amount of voltage that is stepped up or down?
For an ideal transformer, the voltage ratio is exactly the same as its turns ratio. So if, for example, there are twice as many turns on the secondary winding as there are on the primary winding, then the secondary voltage will be twice that of the primary and the transformer will be a 'step up' type.
Why auto transformer is lighter than conventional type?
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
What is transformation ratio of step-up transformer?
The ratio depends on the ratio of the length of the windings and depends on the specific transformer. There is no single answer to this question.
How do you determine transformer turns ratio if the supply source and load is given?
Transformer turns ratio is the ratio of voltages between two windings. For instance, a 24VAC control transformer that runs on 120VAC will have a turns ratio about 5 to 1.
What are facts about a Transformer turn ratio?
Typically a transformer is designed for a specific turn ratio x:y the fact is that is only true if the power is held as designed for that ratio
What are the reasons for conducting transformer turns ratio?
The reason for conducting transormer turns ratio is to determine if the transformer is a step-up or step-down.AnswerTo determine the turns ratio if the turns ratio is unknown.
If a Transformer primary and secondary are equal?
You will have a 1:1 ratio isolation transformer.
Current ratio is opposite than voltage ratio in transformer?
Yes
No-load and full load transformer?
A: a transformer will follow the rule of input output ratio with no load. As soon as a load is applied there will be changes in the ratio
What reference to a transformer the current times the number of turns is called the?
Transformer turns ratio
