In the following circuit, the equivalent capacitance between terminal A and terminal B is:

Asked in NEET 2024 · Capacitor networks

Figure: Capacitor networks
Answer: (3) 2 μF

Step-by-step solution

The four outer capacitors are equal, so the two middle junctions are at the same potential: the bridge is balanced and the middle 2 μF capacitor holds no charge.

Each path from A to B is two 2 μF capacitors in series: (2×2)/(2+2)=1 μF.

The two paths are in parallel: C_AB=1+1=2 μF.

Why the other options are wrong
