The goal is to determine the relationship between current and resistance for simple resistors. To do this we must test how current is affected by different values of resistance. Our independent value is resistance and our dependent value is current. Our constants would be voltage; thus, we must keep the number of batteries used constant. For this experiment I am using four batteries. I am testing 5 different values of resistance or 5 different simple resistors. First I looked at the resistor and recorded the color code. Next I tested the resistance. I did this by attaching a black alligator clip to the negative probe and a red alligator clip to the positive probe. Then I attached an end of the resistor to the red positive alligator clip and the other end to the black negative alligator clip. I set my

Unformatted text preview: multimeter to Ohms and turned on the multimeter. To find the current, I attached a black alligator clip to the negative end of the battery and a red alligator clip to the positive end of the battery. Next, I attached the black alligator clip on the battery to one end of the resistor and an alligator clip to other side of the resistor. Next I attached the black alligator clip with the negative probe to the alligator clip closest to the negative side of the battery and the red alligator clip with the positive probe to the alligator clip closest to the positive side of the battery. Next, I switched the socket, in which the red probe was connected, to the white socket which is used for measuring current. I set my multimeter to Amperes and turned it on. I repeated this for 5 different resistors....
