Jadeen says that you can increase the resistance of a copper wire by hammering the wire to make it narrower and longer. Arnell says that you can increase its resistance by heating the wire. Which one, if either, is correct, and why?
a. Arnell, because the resistivity of the wire increases when it is heated. b. Arnell, because the resistivity of the wire decreases when it is heated. c. Jadeen, because the resistivity of a wire is inversely proportional to its area and directly proportional to its length. d. Jadeen, because the resistivity of a copper wire does not decrease when it is hammered. e. Both are correct because (a) and (d) are both correct.
In 1991, a utility owned a nuclear plant that was online 95% of the year, the oil burning plant was only out for unscheduled maintenance on the air pollution system 15% of the time, and the gas-fired turbines were online 15% of the time
The nuclear plant is rated at 1000 MW, the oil plant at 940 MW, and the turbine at 200 MW. (See Fig. 8.15.) a. What is the total cost of running these three plants for the utility? b. How much would the utility have to charge per kWh to make a profit?
