JEE Mains · Physics · STD 12 - 3. current electricity
The heat generated in 1 minute between points A and B in the given circuit, when a battery of 9 V with internal resistance of \(1 \Omega\) is connected across these points is _________ J.

- A 540
- B 1080
- C 2160
- D 120
Answer & Solution
Correct Answer
(B) 1080
Step-by-step Solution
Detailed explanation
\(i =\frac{9}{3}=3 A\) \(\therefore \quad H_{A B}=i^2 R_{A B} t\) \(=(3)^2 \times 2 \times 60=1080 J\)
