2. A hydroelectric power plant produces an EMF of e(t) = Emax sin(wt) = (5000 V) sin((2π x 60 Hz)t) and is connected to a city (equivalent resistance 1.002) via transmission lines (equivalent resistance 10.0 m2). a. Explain why this a very inefficient arrangement. Calculate any relevant average power outputs. b. Describe quantitatively the transformer that is needed to convert this to a 10 million volt alternating current. Why will this improve efficiency? C. Explain why our power grid is based on AC current rather than DC current.
