1. While out for a walk with his mother, Lance notices a large, cylindrical gray
box high atop a telephone pole. His mother explains that it is a transformer. This
transformer takes 6000 V fromthe power company and steps it down to the 240
V supplied to each of the houses on the street, with the use of a secondary
coil containing 100 turns. How many turns are there in the primary coil?

Consider a transformer, used to recharge rechargeable flashlight batteries, that has 500 turns in its primary coil, 4 turns in its secondary coil, and an input voltage of 120 V. Note that n = 4 (a) Given that the input current I(p) is 0.0256 A, to produce a 3.2 A output current, convert 0.0256 A to milliamps. I(p) = Part (c) What is the power input, in watts? (Explain thoroughly whether or not you use amps or milliamps for this calculation)
The transformer on a utility pole steps the voltage down from 10000 V to 220 V for use in a college science building. During the day, the transformer delivers electric energy at the rate of 10.0 kW. a) Assuming the transformer to be ideal, during that time, what are the primary and secondary currents in the transformer? b) If the transformer is only 90 % efficient (but still delivers electric power at 10.0 kW), how does its input current compare to the ideal case? c) At what rate is heat lost in the nonideal transformer? d) If you wanted to keep the transformer cool and to do this needed to dissipate half of the joule heating of part c) using water cooling lines (the other half is taken care of by air cooling), what should be the rate of flow (in liters per minute) of water in the lines? Assume the input cool water is at 68∘∘F and the maximum allowable output water temperature is 98∘∘F} .
