rc circuits rapid decay lab


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 – on Ch 2. (one of the ground wires were not connected because the two channels of the oscilloscope share a common ground) (Fig.1).
