COMEDK · Physics · 18. Capacitance
A network of capacitors is as shown below. If the voltage supply is 100 V , find the energy stored in the \(6 \mu \mathrm{~F}\) capacitor.

\(C_1=3 \mu F, C_2=6 \mu F, C_3=3 \mu F\) and \(C_4=4 \mu F\)
- A 12 mJ
- B 2.2 mJ
- C 4.2 mJ
- D 1.2 mJ
Answer & Solution
Correct Answer
(D) 1.2 mJ
Step-by-step Solution
Detailed explanation
The circuit consists of a capacitor \(C_4\) in parallel with the series combination of \(C_1, C_2,\) and \(C_3\). First, calculate the equivalent capacitance of the series branch containing \(C_1, C_2,\) and \(C_3\). Let this be \(C_{series}\).…
