COMEDK · Physics · 18. Capacitance
In the network shown in figure, the equivalent capacitance between points \(P\) and \(Q\) is
- A \(1 \mu \mathrm{F}\)
- B \(2 \mu \mathrm{F}\)
- C \(3 \mu \mathrm{F}\)
- D \(4 \mu \mathrm{F}\)
Answer & Solution
Correct Answer
(A) \(1 \mu \mathrm{F}\)
Step-by-step Solution
Detailed explanation
Simplify from right to left. Rightmost section: \(3\mu F\), \(3\mu F\), \(3\mu F\) in series (path \(B \to C \to D \to E\)): \(\dfrac{1}{C_{eq1}} = \dfrac{1}{3} + \dfrac{1}{3} + \dfrac{1}{3} = 1 \Rightarrow C_{eq1} = 1\mu F\) This \(1\mu F\) is in parallel with \(2\mu F\)…
