A. Draw the schematic diagram (circuit diagram) for testing the transformer under load. Include one power analyzer on the supply side of the transformer and another on the load side.
b. Develop a test to determine the polarity markings (high and low terminals) on the two sides of the transformer.
c. Draw the additive and subtractive autotransformer connection diagrams. In each case, use 120 V for the supply voltage and determine the output voltage
