Demonstration 2: The resistance of most conductors increases as the temperature increases. As more current flows through the Current filament of a light bulb, the temperature of the filament gets higher. A light bulb is connected to a variable source of voltage. Sketch on the right your prediction of a graph of the current that flows through the light bulb as the voltage across the light bulb is increased starting from zero. After you have made your prediction, again use the simulation: https://phet.colorado.edu/sims/html/circuit-construction-kit- O dc/latest/circuit-construction-kit-dc_en.html 0 Voltage Click on Lab and construct the circuit. You can look at a picture of the correct circuit here. Adjust the battery voltage in equal 5 volt Voltage(V) Current (A) steps by clicking once on the battery and adjusting the slide 0.0 switch, only this time, increase the resistance of the bulb by 0.5 ohm for each voltage step. Record the values in the table and 5.0 sketch the graph with a dashed line. See how the current through 10.0 the bulb varies and compare it to your prediction. Explain. 15.0 20.0 Does a light bulb obey Ohm's law? 25.0 30.0 35.0 How would you find the resistance of the light bulb at any particular voltage? 40.0 45.0 50.0
