Suppose a wind-powered generator is capable of producing an emf of 1,000 M. To transmit electrical energy over a longer distance, it is desired to step up the voltage from 1,000 IV] to 1,000,000 IV]. What is the ratio of the number of turns in the secondary to the primary (in an ideal transformer) required to step up the voltage to the desired amount? Ns/Np 100 NSN 10,000 NSN 1,000 Ns/Np 100,000

Solution

The required voltage levels -

Primary voltage, Vp = 1000 V

Secondary voltage, Vs = 1000000 V

Now for an ideal transformer,

Vp / Vs = Np / Ns = 1000 / 1000000

=> Ns / Np = 1000

Therefore, third option is the correct answer.
