In the method using the transformers, assume that the ratio of the number of turns in the primary to that in the secondary in the step-up transformer is 1 : 10. If the power to the consumers has to be supplied at 200 V, the ratio of the number of turns in the primary to that in the secondary in the step-down transformer is-
- 200 : 1
- 150 : 1
- 100 : 1
- 50 : 1
Correct answer: 200 : 1
