Apower of 100 kw (105 w) is delivered to the other side of a city by a pair of power lines, between which the voltage is 12,000 v. (a) use the formula p 5 iv to show that the current in the lines is 8.3 a. (b) if each of the two lines has a resistance of 10 ω, show that there is a 83-v change of voltage along each line.
