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





Sagot :

Fantas
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
