JEE Mains · Physics · STD 12 - 3. current electricity
In the network shown below, the charge accumulated in the capacitor in steady state will be ........... \(\mu C\)
- A \(7.2\)
- B \(4.8\)
- C \(10.3\)
- D \(12\)
Answer & Solution
Correct Answer
(A) \(7.2\)
Step-by-step Solution
Detailed explanation
No current will flow in capacitor in steady state, current flowing in the circuit in steady state \(I=\frac{3}{6+4}=\frac{3}{10}\) Potential difference on \(6\,\Omega\) resistance \(V=6 \times \frac{3}{10}=1.8 \text { volt }\) Capacitor will have same potential so charge,…
