Chapter 11, Problem 84P
A consumer has an annual consumption of 1200 MWh with a maximum demand of 2.4 MWh. The maximum demand charge is $30 per kVA per annum, and the energy charge per kWh is 4 cents.
(a) Determine the annual cost of energy.
(b) Calculate the charge per kWh with a flat-rate tariff if the revenue to the utility company is to remain the same as for the two-part tariff.

A lossless uncharged transmission line of length L = 0.45 cm has a characteristic impedance of 60 ohms. It is driven by an ideal voltage generator producing a pulse of amplitude 10V and width 2 nS. If the transmission line is connected to a load of 200 ohms, sketch the voltage at the load as a function of time for the interval 0 < t < 20 nS. You may assume that the propagation velocity of the transmission is c/2. Answered now answer number 2.
Repeat Q.1 but now assume the width of the pulse produced by the generator is 4 nS. Sketch the voltage at the load as a function of time for 0 < t < 20 nS.
Solve this experiment with an accurate solution, please. Thank you.
