A transformer changes the voltage

How a transformer affects the voltage and current ?

Assertion : A step-up transformer changes a low voltage into a high voltage. Reason : This violate the law of conservation of energy.

Is energy produced when a transformer steps up the voltage?

Is energy produced when a transformer steps up the voltage?

Is energy produced when a transformer steps up the voltage?

Statement (A) : Step up transformer converts low voltage, high current to high voltage, low current Statement (B) : Transformer works on both ac and dc.

In step-up transformer the output voltage is 11 kV and the input voltage is 220 V. The ratio of number of turns of secondary to primary is:

In a step - down transformer the input voltage is 22kV and the output voltage is 550V The ratio of the number of turns in the secondary to that in the primary is .
