A transformer has 120 turns on the primary coil and 70 turns on the secondary coil. If the output voltage is 220V, what is the input voltage?

answer : input voltage = 377.143

steps:

Vout/Vin = Ns/Np

p = primary

s = secondary

primary and secondary voltages

are the same as

induced EMF

V is voltage

N is number of turns

output voltage / input voltage = secondary turns / primary turns

220/input voltage = 70 / 120

input voltage * 70 = 220 * 120

input voltage = (220 * 120)/70

input voltage = 377.143
