Capacitance Of A Capacitor Using Reed Switch |
|
Aim : |
|
The aim of this experiment is
to measure the capacitance of a capacitor using a reed switch.
|
|
Circuit : |
|
|
|
Materials : |
|
- A Reed Switch
- A Signal Generator
- A Voltmeter
- A Micro-Ammeter
- A Power Supply
- A Set of Capacitors
- Leads
|
|
Procedure :
|
|
- Set up the circuit shown in the diagram.
- Adjust the frequency (f) of the signal generator to give a smooth switching of the reed relay.
- Record the current (I) in the meter.
- Record the voltage (V) across the coil.
- Repeat the experiment for a number of other capacitors.

|
Conclusion : |
|
You can calculate the capacitance (C) of the capacitor from,
C = I / (f x V)
