We would like to connect a 6 kVA, 120/240 V transformer as an autotransformer to a 120 V source to supply 360 V to a load. A) Draw the circuit. B) What is the maximum load kVA that can be supplied? C) At the maximum load, determine lin. In, and I,. D) What are the possibilities to connect this transformer as a step-down autotransformer and determine the load voltage at each case with the same source voltage of 120 V?
