In 1879, Tesla applied the idea of using high voltages during transmission over distance and lower voltages for home and office using an electromagnetic transformer.

a. What would the ratio of turns of wire in a transformer have to be to transform a voltage from 120 volts to 1000 volts? 

b. Which side would have more turns, low or high voltage? 

c. Discuss the design tradeoff involved in stepping up and stepping down voltages. What are the advantages and disadvantages?
