Determining the Capacitance of a Plate Capacitor Measuring the Charge with the I Measuring Amplifier D

The Parallel Plate Capacitor Experiment is designed to measure the capacitance of a parallel plate capacitor as a function of plate separation with high accuracy. The apparatus features a precision parallel plate capacitor with continuously adjustable plate spacing, allowing students to verify the theoretical relationship between capacitance and plate distance. It provides a practical demonstration of electrostatic principles and capacitor characteristics. Manufactured by Atico Export India.

Principle

The capacitance of a parallel plate capacitor is inversely proportional to the distance between its plates and directly proportional to the plate area. By continuously varying the plate separation and measuring the corresponding capacitance, the theoretical relationship between capacitance and plate spacing can be experimentally verified.

Objectives

• Measure the capacitance of a parallel plate capacitor.
• Study the effect of plate separation on capacitance.
