A transformer with 1760 turns on the primary and 347 turns on the secondary is used in an electric slot car racing set to reduce the input voltage amplitude of 170 V from the wall output. The current in the secondary coil is of amplitude 3.2 A.
What is the voltage amplitude across the secondary coil?
V

What is the current amplitude in the primary coil?
A

V1/V2=170/x=1760/347

x=33.517V

I1/I2=x/3.2=347/1760

X=0.6309 A
