A transformer has turns in its primary coil and turns in its secondary coil. If an alternating voltage of is applied to the primary, what is the secondary output voltage (assuming efficiency)?
Answer and explanation
Correct answer: D.
- Step 1: State the ideal transformer equation: .
- Step 2: Rearrange to solve for secondary voltage: .
- Step 3: Substitute values: .
Answer
.
Why not the others: '' divides by the turns ratio (step-down operation ); '' divides by ; '' multiplies by instead of .
