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?

Sagot :

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

[tex]\frac{V_1}{V_2}=\frac{N_1}{N_2}[/tex]

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

[tex]\frac{240}{V_2}=\frac{1500}{200}\Rightarrow V_2=32V[/tex]

Thus, the output will be 32V
