COMEDK · Physics · 18. Capacitance
In the figure below, the capacitance of each capacitor is \(3 \mu \mathrm{F}\). The effective capacitance between \(A\) and \(B\) is
- A \(\frac{3}{4} \mu \mathrm{F}\)
- B \(3 \mu \mathrm{F}\)
- C \(6 \mu \mathrm{F}\)
- D \(5 \mu \mathrm{F}\)
Answer & Solution
Correct Answer
(D) \(5 \mu \mathrm{F}\)
Step-by-step Solution
Detailed explanation
From figure, \(C_1=C_2=C_3=C_4=3 \mu \mathrm{F} \quad (given)\) \(\because C_4\) and \(C_3\) are in parallel, i.e. \(C_{\text {eq }}=C_4+C_3=(3+3) \mu \mathrm{F}=6 \mu \mathrm{F}\) Now arrangement of capacitors will be as follows \(\because C_1\) is in parallel with the series…
