An RC circuit was assembled according to the circuit diagram shown in Fig. 7.3 of the lab manual.A function generator with the output resistance of about 50 Ohms generating a square waive (f=100 Hz) served as a power supply. The resistor box (set for R=2000 Ohms) was connected in series with a capacitor (C= 0.514 mF). A square-wave signal applied to the circuit was registered on Ch1 of the oscillator, whereas the signal across the capacitor â€“ on Ch 2. (one of the ground wires were not connected because the two channels of the oscilloscope share a common ground) (Fig.1).
