Activity 1: Hand Draw the circuit diagram for one of your simple circuit of a light bulb and a power supply, include the voltmeter and ammeter connection in the diagram. Label all circuit elements along with the voltage and current measurements made. Provide evidence that the voltage drops across ALL elements in your circuit sum to zero. 2 when we measure the voltage so that it hits the red cable first (+), the + 1.61 V. If we move the wires closer to the battery, switching the locations of the red and black wires, the voltage change is -1.61 V. Therefore, it is evident that the sum is Zero. The battery had the same magnitude, only opposite in sign. V battery voltage- lightbulb voltage=0
Activity 1: Graph 3 V vs. I from #1 and #2 measurement. Include legend showing the resistance of the lightbulb. I vs. R from #3 and #4 measurement. Include legend showing the voltage of the battery.
Activity 1: From the observation of the graphs, draw some conclusions from activity 1. From the provided graphs, it's evident that as the resistance increases, the voltage also increases proportionally while keeping the current constant. This relationship is in line with Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them, given constant temperature and other physical conditions. 4
