Measuring I-V curves
Sketch the

curve of the PhET model of a light bulb. (Use the computer to make detailed
quantitative plots. On this sheet make qualitative sketches that show the general behavior of
the
I-V
curve for each device. This is sort of like giving a synopsis of a movie – you don’t
describe the whole plot, but you provide enough detail to convey the essence.):

Procedure
Parallel Circuit 1
Using an Ohm-meter check the values of your resistors and record the values under Equipment and Materials.
Using the Parallel Circuit 1 in Figure 5.1 with R1 = 3.3 kΩ, R2 = 4.7 kΩ and E = 9 volts, calculate the total resistance and record it in the Calculated Total Resistance of the Data Sheet. Then determine the theoretical voltages at nodes A, B, and C with respect to ground. Record these values in Table 5.1.
Apply Ohm’s law to determine the expected currents through R1 and R2. Record these values in Table 5.2. Also determine and record the…
