Suppose we have a 10-V-peak sinusoidal voltage source. Draw the diagram of a circuit that clips off the part of the sinusoid above 5 V and below -4 V.

A crystalline silicon photovoltaic cell has an open circuit voltage of 0.5V and a short circuit current of 1.8 A at Standard Test Conditions. What is the maximum output power at Standard Test Conditions and at a cell temperature of 50oC? What is the percentage decrease in power per oC? Assume a Fill Factor of 0.70 at 25oC. (As a rule of thumb for crystalline silicon solar cells, the increase in short circuit current is about 0.058% per oC while the decrease on open circuit voltage is 0.30% per oC and decrease in the fill factor is by 0.15% per oC).
