PURPOSE: To demonstrate a reasonably fast RC circuit.
DESCRIPTION: Using a decade resistance box and a decade capacitor box a series RC circuit is produced. (1) It can be driven by a slow square wave and the voltage across the capacitor as the capacitor charges can be observed using the dual trace scope. (2) It can be driven by a sine wave and the phase shift between the voltage across the capacitor and the sine wave from the oscillator can be seen on the dual trace scope. See circuit below.
SUGGESTIONS:
REFERENCES: (PIRA 5F30.20)
EQUIPMENT: Decade capacitor box, decade resistor box, oscillator, and dual trace scope on scope/TV cart.
SETUP TIME: 5 min.
