Question

3. The secondary voltage is 220 Volt and primary voltage is 110 volt, then the ratio of the secondary coil to primary coil is

Answer 1

Here is answer of the above question;-

Secondary voltage (Vs) =220 V

Primary Voltage (Vp) = 110 V

We have transformation ratio

K= Vs/Vp=Ns/Np

Where ,

Ns= secondary winding turns

Np=primary winding turns

K is transformation ratio which is the ratio of secondary voltage to primary Voltage or number of turns on secondary winding to the number of turns on the primary winding.

K=Ns/Np. =220/110.

Ns / Np= 2

The ratio of secondary coil to primary coil is 2.
