How does the turns ratio affect the output voltage of a transformer?.
- A.The output voltage is directly proportional to the turns ratio
- B.The output voltage is inversely proportional to the turns ratio
- C.The turns ratio has no effect on the output voltage
- D.The output voltage is equal to the input voltage
Model answer
What a good answer should say
- The output voltage is directly proportional to the turns ratio
Explanation
Why this works
In a transformer, the output voltage is directly proportional to the turns ratio. This means that if the number of turns in the secondary coil is greater than in the primary coil, the output voltage will be higher, and vice versa.
