A transformer has a primary coil with 600 turns and a secondary coil
with 300 turns. If the output voltage is 320 volts, what is the input
voltage?A. 8 volts B. 150 volts C. 640 volts D. 600 volts

Accepted Answer

Number of turns in the primary Np = 600 Number of turns in the secondary Ns = 300Output voltage Es = 320 voltsInput voltage Ep = ? Assuming the transformer to be ideal,Np/Ns = Ep/EsEp/Es = 600/300 = 2Ep = 320*2 = 640 volts
