An Experiment to Demonstrate that capacitance depends on common area, distance between plates, and the nature of the dielectric

Draw diagram (A) of the experiment

…

Method (A) (Step 1)

Set up apparatus as shown and decrease the common area

Result (A)

Leaves of the GLE diverge

Conclusion (A)

Capacitance depends on the common area

The higher the voltage the … they diverge

More

Draw diagram B

…

Method (B) (Step 1)

Set up apparatus as shown and decrease the separation of the plates

If there is a decrease in Area there will be an … in capacitance

Decrease

Result (B)

Leaves of GLE converge

Conclusion (B)

Capacitance depends on the separation/distance between the plates

If there is a decrease in distance/separation there will be a … in capacitance

increase

…

Method (C) Step 1

Set up apparatus as shown and insert a dielectric with a lower permittivity

Results (C)

Leaves of the GLE divergeC

Conclusion (C)

Capacitance depends on the permittivity of the dielectric

If there is a decrease in permittivity there is a … in capacitance

Decrease

If there is a decrease in area there is a … in voltage

Increase

If there is a decrease in distance/separation there will be a … in voltage
