STANDARD Physics Capacitors MCQ Question
Type: MCQ-numerical-Medium
A network of four 20 μF capacitors is connected to a 600 V supply as shown in the figure. The equivalent capacitance of the network is
A
30.26 μF
B
20 μF
C
26.67 μF
D
10 μF
Correct Answer
Option C
Detailed Explanation
From the figure, C₁, C₂, C₃ are connected in series, giving 1/Cₛ = 1/20 + 1/20 + 1/20 = 3/20 μF. Therefore, Cₛ = 20/3 μF. Cₛ is in parallel with C₄, so the equivalent capacitance Cₑq = Cₛ + C₄ = 20/3 + 20 = 26.67 μF.
