C10 Measurement of capacitance by reed switch
Procedure
. Connect the circuit. Set the resistance of the variable resistor at its maximum value. Record the reading of the voltmeter.
Voltage = ______ 5.9 __________V
4. Decrease the resistance of the variable resistor slowly until the current shown on the microammeter does not increase any more. Record the reading of the microammeter.
5. Repeat steps 3 and 4 with the other frequencies of the signal generator from 400 Hz to 10 Hz. Tabulate the results.
