Material:

B1 - 9 to 12 V source

R1 - 10 k ohm x 1/8 W - resistor

R2 - 470 k ohm x 1/8 W - resistor R3 - 100 ohms x 1/8 W - resistor

P1 - 1 M ohm - potentiometer

C1 - 10 nF for the oscilloscope or 1 uF for the multimeter

 

Procedure

The test circuit is given in the figure below.

 

 


 

 

 

By adjusting P1 we should observe the oscillating instrument needle or the waveform generated on the oscilloscope screen.
