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 \(C_4=4 \mu F\)

  1. A 12 mJ
  2. B 2.2 mJ
  3. C 4.2 mJ
  4. D 1.2 mJ
Verified Solution

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 \(C_{series}\).…
