The equivalent capacitance between A and B in the given figure is
Options
- A2 3 F
- B2 F
- C4 F
- D4 3 F
Correct answer
D. 4 3 F
Step-by-step solution
For symmetry potential difference across each capacitor of capacity is zero. aligned & 1 C _ eq = 1 1 + 1 3 + 1 9 + 1 27 + & =1+ 1 3 (1+ 1 3 + 1 9 + 1 27 + ) & =1+ 1 3 [ 1 1- 1 3 ]=1+ 1 3 3 2 = 3 2 & C _ eq = 2 3 F then C _ AB =2 2 3 = 4 3 F aligned
