- 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…A resistor R1 is connected in parallel with a second resistor R2 = 0.5R1. This parallel configuration is then connected in series with R3 = 2R1 and across a cell with voltage V = 9V.
