A transformer has 200,000 windings in its primary coil and uses 10,000V AC input

How many windings would be needed to produce at output of 120V AC? Is this a step down or step up transformer?

Input voltage = 10000 volt

shamim · Answer

Output voltage = 120 volt

shamim · Answer

Which is bigger?

shamim · Answer

Which is bigger between 
120 and 10000

shamim · Answer

If output voltage is greater than input voltage,  then it is stepup transformer

shamim · Answer

If output voltage is less than input voltage, then it is called step down transformer

shamim · Answer

Required equation is
E*primary/E*secondary = Np/Ns

Before I close this I want to say that I got the answer of 2,400 windings and a step down transormer.
