Question

Suppose a transformer's primary coil has 10 times as many turns as its secondary coil. Why does the transformer normally deliver only about 1/10th of the voltage it receives

Answer 1

The voltage induced is directly proportional to numbers of turns in each coil.

Step-by-step explanation:

In transformers, the change in magnetic flux is due to the voltage induced in secondary coil. Both coils has equal number of turns and the total induced voltage is directly proportional to number of turn in each. The secondary coil have less number of turns so, it will have less voltage.
