An American traveler in China carries a transformer to convert China's standard 220 V to 120 V so that she can use some small appliances on her trip.
a. What is the ratio of turns in the primary and secondary coils of her transformer?
Np / Ns =
b. What is the ratio of input to output current?
Iin /Iout =
c. How could a Chinese person traveling in the United States use this same transformer to power her 220 V appliances from 120 V?
