Experiment 2: Simple DC Circuits; Resistors and Resistive Sensors Shayan Rizvi Department of Electrical and Computer Engineering, University of Connecticut, Storrs, Connecticut 06269 DC circuits were set up in series and parallel to test for fundamental circuit properties like current and voltage. A 10 and 20 (Ω) resistor were set up in series where the voltage measured was 0.667 and 1.344 V respectively from a 2.01 V voltage supply. Using the same resistors but in parallel current measurements of 0.5 and .25 mA were recorded respectively with a total current source of .75 mA. The idea of converting light and temperature to electrical resistance was then explored using a photoresistor and a thermistor. For the photoresistor the resistance changed from 1.59 to 16.87 k Ω from light to dark. The thermistor changed from 4.03 to 3.05 k Ω from cold to warmer temperatures. Introduction. This experiment demonstrated Kirchhoff’s voltage and current laws (KVL and KCL). Where the KVL states the summation of the
