If a step-up transformer has a primary coil with 40 turns, how many turns would be required in the secondary coil in order to increase the voltage from 80 volts to 160 volts?

twice the voltage means twice the turns
N1 = # of turns on primary.
N2 = # of turns on secondary.
N1/N2 = V1/V2.
40/N2 = 80/160.
N2 = ?
N2 = # of turns on secondary.
N1/N2 = V1/V2.
40/N2 = 80/160.
N2 = ?
