\fANALYSIS - Graph your data with voltage on the yaxis, and current on the xaxis. Make sure the equation for your best t line is displayed on the graph. FQ4: Is your plot linear? If not, are there any regions where it does appear to be linear? FQS: How does the V-I plot for the light bulb differ from that of the resistor? Consider the following: the resistance of a conductor (such as a wire, a resistor, or a tungsten light bulb lament) not only depends on the type and shape of material used, but also the temperature. A simple model used to describe this temperature dependence is given by: if}; = 1 + cm, (3.2) where R f is the resistance of a piece of material at a nal temperature, R, is the resistance of the material at an initial temperature, AT is the change in temperature, and a is a constant: the temperature coefcient of resistance. For tungsten:2 00045 a = 00 FQB: How does the temperature dependence of resistance explain the trends you see on the V-I plot for your light bulb? (You do not need to calculate anything here, but give a qualitative answer based on the shape of your V-I plot.) (3.3) 'Q'i': Estimate the resistance of the \"hot\" light bulb from your V-I plot. How does this value compare to the resistance of the \"cold\" bulb, R0
