Physics 152 Lab #3 DC Circuits: Voltage, Current and Resistance Abstract: Lab 3 Questions: 1.Think about about a quaint old cottage. When the lightbulb in the living room burns out, the television turns off. What does this mean about the wiring in the living room? This means that things are wired in series so if one part of the circuit fails all of the parts do because the voltage cannot travel through a burn out path way. Since there is no alternative route like there are in parallel circuits the whole system stops working until you find the not working part. While if things where in parallel you could tell when the lightbulb burns out and adress that instead of checking every part in the circuit. 2.(1 point) Is there a linear relationship between voltage and position of the slider on the rheostat (slide wire resistor)? Why might this be the case? Please attach the corresponding graph. There is a linear relationship because the this proves Ohm’s law V=IR. So as the position
