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