Question by steve00878: A step-down transformer is to be used to convert an ac voltage of 105 V to 6 V to power an electric train. If?
A step-down transformer is to be used to convert an ac voltage of 105 V to 6 V to power an electric train. If there are 420 turns in the primary coil, how many turns should there be in the secondary coil?

Best answer:

Answer by jrrymiller
The voltage ratio is the same as the turns ratio.
6/105 = X/420
X = 6*420/105 = 24 turns
