slope (10
Ω
) = ________ Volts/Amps
Optional
➀ Replace the 10
Ω
resistor with the 100
Ω
resistor.
➁
Click the “Increase Sweep Speed” button ( ) in the Scope display to change the sensitivity
of the horizontal axis to 0.010 v/div.
➂ Repeat the experiment. Record the new slope.
slope (100
Ω
) = ________ Volts/Amps
Part B – Light Bulb Filament
PART I: Computer Setup for Light Bulb Filament
For this part of the activity you will use the filament of a light bulb as the resistor. In the Com-
puter Setup you will change the Amplitude and Frequency of the output AC waveform. You will
also change some of the settings on the Scope display.
➀ Click the Signal Generator window to make it active.
➁
Click on the Amplitude value to highlight it. Type in “2.5” as the new value. Press the “enter” key.
