JEE Main2016PhysicsCapacitanceActual
Figure shows a network of capacitors where the number indicates capacitances in micro Farad. The value of capacitance C if the equivalent capacitance between point A and B is to be 1 μ F is :
Options
- A32 23 μ F
- B31 23 μ F
- C33 23 μ F
- D34 23 μ F
Correct answer
A. 32 23 μ F
Step-by-step solution
C e q of circuit = 32 9   μF e x c l u d i n g   C Now 32 9  μF is in series with   C so, 1 C e q = 1 C + 9 32 = 1 ⇒       C = 32 23   μF
