Introduction
For capacitors in the parallel combination, the total capacitance C is given by: C = C1 + C2 + C3 where C1, C2 and C3 are individual capacitances. Also in the parallel combination, potential difference between the two plates is the same on each capacitor.
Pre-Requisites:
Capacitors, Capacitance, Plate charge, Potential difference
Activity:
Understanding the concept of parallel combination of the capacitors. Calculating the effective capacitance of the parallel combination of the capacitors.
Real Life Question:
How to increase the equivalent capacitance of group of capacitors?
