the primary voltage of a transformer is 120 volts and its primary coil is 270 turns. calculate the output voltage if the secondary coil has 180 turns

Answer 1

To find the output voltage of the transformer, we can use the formula for the turns ratio:

Turns ratio = Ns / Np

where Ns is the number of turns in the secondary coil and Np is the number of turns in the primary coil.

In this case:
Ns = 180
Np = 270

Turns ratio = 180 / 270
Turns ratio = 0.66667

The output voltage can be calculated using the turns ratio:

Output voltage = Turns ratio * Primary voltage
Output voltage = 0.66667 * 120
Output voltage = 80 volts

Therefore, the output voltage of the transformer is 80 volts.
