JEE Mains · Physics · STD 12 - 3. current electricity
In the electric network shown, when no current flows through the \(4\, \Omega \) resistor in the arm \(EB\), the potential difference between the points \(A\) and \(D\) will be ............... \(V\)
- A \(6\)
- B \(3\)
- C \(5\)
- D \(4\)
Answer & Solution
Correct Answer
(C) \(5\)
Step-by-step Solution
Detailed explanation
As no current flows through arm \(E B\) then \(\mathrm{V}_{\mathrm{D}}=0\, \mathrm{V}\) \(\mathrm{V}_{\mathrm{E}}=0\, \mathrm{V}\) \(\mathrm{v}_{\mathrm{B}}=-4 \,\mathrm{V}\) \(\mathrm{V}_{\mathrm{A}}=5 \,\mathrm{V}\) So, potential difference between the points \(A\) and \(D\)…
