Question 13Electricity & Electronics - Assistant Engineer

The correct answer is A) The voltage supplied to the primary side is greater than the voltage produced by the secondary side. This is correct because in a step-down transformer, the primary winding has more turns than the secondary winding. This causes the voltage on the primary side to be stepped down or reduced on the secondary side, in accordance with the transformer equation V1/V2 = N1/N2, where V1 and V2 are the primary and secondary voltages, and N1 and N2 are the number of turns on the primary and secondary windings, respectively. The other options are incorrect because B) and C) describe the opposite relationship, where the current and kVA are stepped down rather than the voltage, and D) describes a step-up transformer, where the voltage on the secondary side is higher than the primary side.
