Question

The primary of a step-down transformer connected to a 240 V source has 1500 turns. The secondary has 200 turns. What is the output voltage of this transformer?

Answer 1

The relation of voltage and coil turns on an ideal transformer can be written as:

`(V_1)/(V_2)=(N_1)/(N_2)`

Thus, for our data we can replace the values and we'll get:

`(240)/(V_2)=(1500)/(200)\Rightarrow V_2=32V`

Thus, the output will be 32V
