The high-voltage power lines come in from the left. They connect to the large grey transformer on the pole, and from there, two other wires go out to the right and on to the house. The voltage into the transformer is probably around 10,000 V, stepped down to the output of 240 V to operate the appliances in the house. Suppose that if everything is turned on in the house at once, the total current from the transformer reaches 80 A. Since the output current is 80 A at 240 V, what current must move in to the transformer on the high voltage side
