What is the charge on \(15\mu F\) in the circuit given?
- A \(230\ \mu\text{C}\)
- B \(260\ \mu\text{C}\)
- C \(130\ \mu\text{C}\)
- D \(160\ \mu\text{C}\)
Answer & Solution
Correct Answer
(C) \(130\ \mu\text{C}\)
Step-by-step Solution
Detailed explanation
From the given circuit diagram, the \(15\mu F\) and \(30\mu F\) capacitors are connected in series. The equivalent capacitance of this series branch is: \(C_s = \dfrac{15 \times 30}{15 + 30} = \dfrac{450}{45} = 10\mu F\) This series branch is connected directly across the…
