Parallel Plate Capacitor

Chapter-2|Electrostatic Potential and Capacitance| NCERT 12th Physics:

Parallel Plate Capacitor:

The simplest and the most widely used capacitor is the parallel plate capacitor. It consists of two large plane parallel conducting plates, separated by a small distance.

If q is the charge on each plate and A be the area, then

QdA3XEXKJMeE5fMHEEMWE3S0


From the formula it is clear that for high capacitance.

(I) The area of conducting plates should be large.

(II) Distance between two plate should be very small.
