Each plate of a parallel plate capacitor has a charge q on it. The capacitor is now connected to a batter. Now:
Assertion : If three capacitors of capacitance $C_1 < C_2 < C_3$ are connected in parallel then their equivalent capacitance $C_p > C_s$
Reason : $\frac{1}{C_P}=\frac{1}{C_1}+\frac{1}{C_2}+\frac{1}{C_s}$
→Reason : $\frac{1}{C_P}=\frac{1}{C_1}+\frac{1}{C_2}+\frac{1}{C_s}$
