CBSE · Class 12 · Physics · Electrostatic Potential and CapacitanceTwo capacitors of capacitances $C1$ and $C2$ are connected in series. Their equivalent capacitance is:
Step-by-Step Solution
In series combination, $\frac{1}{C_{eq}} = \frac{1}{C_1} + \frac{1}{C_2} \implies C_{eq} = \frac{C_1 C_2}{C_1 + C_2}$.
