What is the name of the device that uses induction to change voltage values in an AC circuit?
A) A transformer
B) A rectifier
C) An amplifier
D) A voltage modulator
E) An AC generator
Homework Answers
Answer is A) Transformer
Since transformer uses faradays law of electromagnetic induction to induce voltage in the secondary side ,that voltage depends in number of turns in primary and secondary i.e secondary voltage is given by
VSecondary =Vprimary *(Nsecondary/Nprimary)
