Is Ohm's Law verified for the resistor? (Hint: Is your graph linear? What does this mean in terms of the formula for Ohm's Law?)| 2. Are the resistance values measured by the Ohmmeter and the slope of the graph within the tolerance limits specified by the colour coding on the resistor? Show your calculations or explain your reasoning. 3. You have three values for the resistance of the resistor. Briefly discuss how the three values compare, and which you think is the closest to the true value (and why). 4. What happens to the brightness of the light bulb as the voltage increases? How did the brightness compare to the current observed on the ammeter? 5. What happens to the resistance of the light bulb as the temperature of the light bulb increases (increasing voltage)? (Hint: look at the shape of the graph. Is the slope increasing, decreasing or linear?) 6. Discuss whether or not the light bulb verifies Ohm's law. (Hint: Think about the mathematical form of Ohm's Law and your answer to question 5.) 7. Evaluate your hypothesis. Make sure to use your results to refute or verify your hypothesis. 8. What is the value of this resistor in ohms? Show your work. Resistor 12 volt (R) battery Voltmeter indication = 12.3 volts Ammeter indication = 4.556 milliamps 9. Why are you able to measure resistance with just an ohmmeter? Why doesn't it need to be connected in a circuit? 1-4 10. What new questions do you have after doing this lab? If you could extend this lab what else would you like to find out with this equipment? What new hypothesis could be tested?Table 1: Voltage and resistance for the resistor in the variable power supply experiment.
