Transformation of voltage

A current of 0.5 A flows through the transformer's primary coil connected to a voltage of 120 V. Calculate the voltage and current in the secondary coil if the transformation ratio is equal to the number 5.

Correct answer:

U2 =  600 V
I2 =  0.1 A

Step-by-step explanation:

U1=120 V I1=0.5 A  n=5  U2=n U1=5 120=600 V
P=U1 I1=120 0.5=60 W  P = U2 I2  I2=P/U2=60/600=0.1 A
