Choose the incorrect statement from the following:
- A A transformer can produce ac power
- B A transformer cannot work on de
- C In a transformer when ac voltage is stepped up x times, the alternating current reduces to \(1 / x\) times
- D A transformer cannot change the frequency of alternating current
Answer & Solution
Correct Answer
(A) A transformer can produce ac power
Step-by-step Solution
Detailed explanation
A transformer transfers AC power, it does not produce it. Therefore, "A transformer can produce ac power" is the incorrect statement.
