Capacitance

Used to show that the capacitance of a parallel plate capacitor depends on the distance between two plates.

APPARATUS:
LOCATION:
     Variable Parallel Plate Capacitor
P6
     Electrometer
P2
     Battery  


Connect the power supply between the two plates. Measure the voltage across a charged capacitor using the electrometer. Change the distance between the 2 plates and each time measure the voltage across the capacitor. Show that the distance between the 2 plates of a capacitor determines the capacitance.
