The transformer

The primary coil of the transformer has 1100 turns and is connected to a voltage of 220 V. How many turns does the secondary coil have when it has a voltage of 55 V?
Determine the transformation ratio and decide what the transformation is.

Correct answer:

n2 =  275
k =  0.25

Step-by-step explanation:

n1=1100 U1=220 V U2=55 V  U1:U2=n1:n2  n2=n1 U1U2=1100 22055=275
