Question

(3) Plot on two separate plots your vollage-vs-currnt data for 1) the resistor and 2) the light bulb. For each plot, answer the following: 1. a. (1) Is the plot linear? If so, what physical quantity does the slope represent? b. (1) If the plot is linear, draw an estimated best-fit line and measure its slope. If the plot is not linear, approximate the plot with two or three lines. Sketch these lines and measure their slopes individually. Show all calculations. (1) Is this object (the resistor or light bulb) ohmic? Explain how the V-vs-l plots help you answer this. c. 2. (2) Based on these plots, what is the resistance of the resistor, and what can you say about the resistance of the light bulb as a function of current?

Explanation / Answer

Solution) first graph is linear starting from the origin .

In this case we can say current is proportional to applied voltage

So it's slope gives resistance

From V=IR

Graphs are not so clear I'm sorry for this PART

Lastly bulb is non ohmic device since it do not follow ohms law

Resistor is ohmic we can say from the graph which is linearly increasing from zero
