Build the RC circuit shown below. Use a 10-VP-P, 1-kHz square wave and adjust the oscilloscope for a “good” view of the voltage across the capacitor. Be sure to adjust your 'scope so the full steady-state voltage is visible, or else you will obtain erroneous results. Sketch two periods of the voltage across the capacitor. Measure the time constant (τ) using the oscilloscope and the “63% rule”; ask your lab instructor if you do not know how to do this. Measure the steady-state output voltage. + 1 kΩ Vout0.1 µFV = 10 VP-P f = 1 kHz τ = __________ sketch: © 2007 Simon J. T1 kΩVSS = ______ ritschler. All Rights Rese+ − ____ rved. 2. Now build the RC circuit shown below. Use the same input signal, but this time sketch the capacitor current by looking at the voltage drop across the series 1-kΩ resistor, which will be in direct proportion to the current by Ohm's Law. Sketch two periods of the signal and measure the time constant, again using the 63% rule. Is it the same τ as that found in the previous problem? Why or why not?
