JEE Mains · Physics · STD 12 - 3. current electricity
In the given figure, the value of \(V_{0}\) will be \(.....V\).

- A \(3\)
- B \(4\)
- C \(40\)
- D \(8\)
Answer & Solution
Correct Answer
(B) \(4\)
Step-by-step Solution
Detailed explanation
By nodal analysis \(\frac{V_{0}-2}{1 k \Omega}+\frac{V_{0}-4}{1 k \Omega}+\frac{V_{0}-6}{1 k \Omega}=0\) \(3 V _{0}-12=0\) \(V _{0}=4\)
