Section 1: Purpose and Introduction Section 2: Experimental DetailsIn this experiment there was the same text conducted with three different types ofresistors: a carbon resistor a dedicated box and a light bulb. The current was measured withammeter and the voltage was measure with a voltmeter. The experimental resistance of eachdevice was measured using a graph of current vs voltage. First the decade box was tested, andthe setting was used at 350 Ω. The circuit was set up exactly how shown in Figure 1. Thevoltmeter was set to the voltmeter mode and the ammeter was set into ammeter mode. Thecurrent was measured in milliamperes for this experiment . The power supply wasswitched on and then the output voltage was adjusted by 1 volt and the reading weremeasured every 1 volt until a maximum of 10 volts was reached. The theoretical for thededicator box is determined by the setting used which was 350 Ω. After a device wasmeasured the current and voltage were checked to be at 0 output before switching resistors.The above procedure was repeated for the carbon resistor by replacing the dedicator box withthe resistor. The bands on the carbon resistor were read and were represented as the range ofwhere the resistance should be within. The theoretical for the carbon resistor was measured
directly with the multimeter. The next device was a lightbulb that was also connected with a50-ohm resistor in series so the lightbulb will not break apart. The same steps were repeatedusing the lightbulb. Figure 1 depicts the set up of the circuit.
