Question 51
Which of the following will happen in a transformer when the number of secondary turns is greater than the number of primary turns?
(a) The voltage gets stepped up
(b) The voltage gets stepped down
(c) The power gets stepped up
(d) The power gets stepped down
The correct answer is (a) The voltage gets stepped up
Explanation: The voltage transformation ratio is the ratio of the number of secondary turns to that of the number of primary turns. When the transformation ratio is greater than 1, the step-up operation occurs.
