Q4. a solar PV module with 36 cells, each with size 12cmx12cm, are connected in series. Calculate the following for the above Module, A. Total Output Voltage B. Total Current Output C. Total Power Output

2. Three resistors are connected to voltage source with output voltage 8.00 V such as R2 = 2.50 N and R3 = 4.00 n are in series and this combination is in parallel with R, = 9.5.0 N. A) Find the total %3D resistance. B) What is the current through resistance R2? C) What is the IR drop of potential on R2. D) What power is dissipated on R2?

2. A 12V battery makes 1.5A of current through a 40, 30, and a 102 resistor. a. How much power does the battery supply? 1.5A AV=12V 2b. How much power is dissipated by the 402 resistor? V=OV 3Ω www 5 122 www V=? 4Ω 1.5A 2c. If the potential at the negative end of the battery is OV, what is the potential V at the star?

As students are conducting an investigation of simple circuits, they notice that when they add additional batteries to their circuit, they can cause a 1.5 Watt light bulb to burn out. They decide to set up an experiment to determine how voltage and power are related. Which of the following procedures would best help them answer their question about voltage and power? O A. d. The students could measure the heat given off by their light bulb before it burns out to determine how much work is being done by the bulb. O B. b. The students could choose light bulbs with different wattage (power) ratings and try each one with a set number of batteries. They could separate the light bulbs that burned out from those that stayed lit and understand how a certain amount of voltage affects bulb life. O C. C. The students could use a voltmeter to measure the voltage going through the bulb at the moment it burns out to confirm that the bulb is getting the full voltage of the battery. They could use…
