A transformer cannot raise or lower the voltage of a D.C. supply because________?
Anone of the above
BFaraday’s laws of electromagnetic induction are not valid since the rate of change of flux is zero
Ca D.C. circuit has more losses
Dthere is no need to change the D.C. voltage
Correct answer
B. Faraday’s laws of electromagnetic induction are not valid since the rate of change of flux is zero
Explanation
The correct answer is Faraday’s laws of electromagnetic induction are not valid since the rate of change of flux is zero.
