Example 14.32. In a series-parallel circuit, the parallel branches A and B are in series with C. The impedances are: $Z_A = (4 + j3)$; $Z_B = (4 - j \frac{16}{3})$; $Z_C = (2 + j8)$ ohm. If the current $I_C = (25 + j 0)$, draw the complete phasor diagram determining the branch cur- rents and voltages and the total voltage. Hence, calculate the complex power (the active and reac- tance powers) for each branch and the whole circuits. (Basic Electricity, Bombay Univ.)

2. Comprehensive problem (1) Water is pumped to a reservoir of 100m high using power from PV panels. Water flows down to generate electricity at night. A ranch needs 20 kW of power for 16 hours at night. How big (volume) the reservoir needs to be? Assume 90% of potential energy from water is converted to electrical energy. g=9.8 m/s$^2$, P$_{water}$= 1000kg/m$^3$. (5 points) (2) If solar panels provide electricity to the pump for 8 hours, how big area the solar panels should have? Assume solar panel efficiency is 10% and solar energy density on the panel is 900W/m$^2$. (5 points) (3) If the ranch is fully relying on solar panels in the day and the energy storage for the night with a steady power of 20 kW, how big the area of solar panels is needed? (5 points) 3 \"cosine effect\" of solar panels

5. Consider the maximum directed cut problem from the previous question. We say that an instance of the directed cut problem is balanced if for each vertex i ? V, the total weight of arcs entering i is equal to the total weight of arcs leaving i. Give an ?-approximation algorithm for balanced maximum directed cut instances, where ? is the same performance guarantee as for the maximum cut problem, i.e., $\alpha = \min_{x: -1 \le x \le 1} \frac{\frac{1}{\pi} \arccos(x)}{\frac{1}{2}(1 - x)}$
