An ideal transformer has 1000 turns on its primary and 50 turns on its secondary. The primary is connected to 230 V a.c. What is the secondary voltage?
Answer and explanation
Correct answer: D. 11.5 V
- Step 1: . Step 2. V. Answer: 11.5 V. Why not the others: 4600 V uses the turns ratio upside down; 5.8 V halves the right value; 23 V uses 100 turns on the secondary.
