Capacitors: Practice Problem & Solution

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Capacitors. Understanding the underlying formula is key to arriving at the correct answer below:

Connecting two $4 \mu F$ capacitors in series gives an equivalent capacitance of $2 \mu F$. Adding the third $4 \mu F$ capacitor in parallel gives a total of $2 \mu F + 4 \mu F = 6 \mu F$.
