Rc Circuit - 100 Microsecond Time Constant


To demonstrate a reasonably fast RC circuit.


Decade capacitor box, decade resistor box, oscillator, and dual trace scope on scope/TV cart.


Setup Time

5 min.




    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. ◙◙
