  2. B \(6\)
  3. C \(8\)
  4. D \(10\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(10\)

Step-by-step Solution

Detailed explanation

Applying \(KCL\) at point \(P,\) \(\frac{V-0}{6}+\frac{V-90}{5}+\frac{V-140}{20}=0\) \(\Rightarrow 10 {V}+12 {V}-1080+3 {V}-420=0\) \(\Rightarrow {V}=60\) \(\therefore \text { Current in } 6 \Omega=\frac{{V}-0}{6}=10 {A}\)
