An American traveler in Kenya carries a transformer to convert Kenya's standard 240 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? (b) what is the ratio of input to output current? (c) How could a Kenyan traveling in the United States use this same transformer to power her 240 V appliances from 120 V?
