012-05892A AC/DC Electronics Laboratory

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.
