Question 462Electricity/Electronics - QMED70% to pass
Which of the following statements is true concerning step-down transformer operation?
AI Explanation
The correct answer is B) The voltage supplied to the primary side is greater than the voltage produced by the secondary side.
In a step-down transformer, the primary winding has a greater number of turns than the secondary winding. This results in the voltage supplied to the primary side being greater than the voltage produced by the secondary side, in accordance with the transformer equation: Vp/Vs = Np/Ns, where Vp and Vs are the primary and secondary voltages, and Np and Ns are the number of turns in the primary and secondary windings, respectively.
The other options are incorrect because:
A) is the opposite of how a step-down transformer operates.
C) and D) describe the current relationships in a step-down transformer, not the voltage relationships.
