OS: A photovoltaic (PV) module is made up of 36 identical cells, all wired in series. With one sun insolation, each cell has short-circuit current ISC 3.4 A and at 25 oC its reverse saturation current is 10 =6 x 10-10 A. The system has a parallel shunt resistance RSH = 6.6 2 and series resistance RS = 0.005 2 as shown in Figure Q8. Find the voltage, current, and power delivered when the junction voltage of each cell is...

4. A consumer has income I = 120. She consumes the goods V (Veggies) and M (Meat), which have prices Py = 6 and PM = 4 respectively. (a) Use the above information and plug it into the budget re- striction: PV V + PMM = I. Illustrate it in a figure, with V on the horizontal axis. How does the budget line change if the price of M falls so that PM = 2? Show in the figure. (b)...
