You have 6 PV panels that each have the same I-V curve (ISC = 5.5 A, VOC = 45 V). (a) How many connection configurations that use all 6 panels are possible? Draw each one. (b) Draw the I-V curves for each of the configurations on one graph. You may draw the curves by hand or use a software of your choice. Clearly label each curve. (c) Assume you are to power a 2.5 Ω load with the panels. Knowing that dimmer sunlight reduces the current output of the cells but not the output voltage, what configuration would be best if you were to build it? Explain your answer.

Refer to the figure below in which surge protectors p and q are used to protect an expensive high-definition television. If there is a surge in the voltage, the surge protector reduces it to a safe level. Assume that each surge protector has a 0.94 probability of working correctly when a voltage
surge occurs. Complete parts (a) through (c) below.

Parallal Configuration
a lf the two surge protectors are arranged in series, what is the probability that a voltage surge will not damage the television?
Do not round.)
b. If the two surge protectors are arranged in parallel, what is the probability that a voltage surge will not damage the television?
(Do not round.)
c. Which arrangement should be used for better protection?
O The series arrangment provides better protection because it has a higher probability of protection.
