What is the voltage output of a transformer with a 500-turn primary and a 1500-turn secondary when 120 VAC is applied to the primary?
Pick an answer to check it.
Answer: A. 360 volts
Voltage scales with the turns ratio: Es = Ep x (Ns / Np) = 120 V x (1500 / 500) = 120 x 3 = 360 V.
Tip: Voltage follows turns: 3 times turns, 3 times volts.
