Question

What is the effective capacitance between points
X and Y?
​

Answer 1

Answer:

Net capacitance = 6μF

Explanation:

In this form of arrangement, no current passes through the 20μF capacitor.

This arrangement is similar to that of the Wheatstone bridge arrangement.

The capacitors between A and B are connected in series and these capacitors are connected in parallel with the capacitors between C and D.

Capacitance between A and B

1 /C1 = 1/6 + 1/6

C1 = 3μF

Capacitance between C and D

1 /C2 = 1/6 + 1/6

C2 = 3μF

Net capacitance = 3 + 3 = 6μF
