Refer to the circuit diagram given below. The heat generated across the \(6\,\Omega\) resistance in \(100\) second is \(\dfrac{\alpha}{100}\) J. The value of \(\alpha\) is _______. (Nearest integer)
- A 3477
- B 3488
- C 3492
- D 3498
Answer & Solution
Correct Answer
(A) 3477
Step-by-step Solution
Detailed explanation
Taking the right-hand wire as the reference node at \(0\text{ V}\), let the left junction (where the \(3\,\Omega\), \(4\,\Omega\) and \(6\,\Omega\) resistors meet) be Node A at potential \(V_A\). Bottom branch: The positive terminal of the \(2\text{ V}\) battery is at the…
