alleryहें . दोन 12 Ω प्रतिरोधक 12 V च्या आडवें चलतात: पयलीं 1 मिण्टांखातीर माळेंत, मागीर 1 मि. वट्ट खंयची ऊर्जा वापरतात?
A1800 J
B1080 J
C720 J
D1440 J
Answer & Solution
Correct answer: A. 1800 J
हें .
माळेच्या पांवड्यांत (12²/24) × 60 = 360 J आनी समांतर अवस्थांत (12²/6) × 60 = 1440 J, वट्ट 1800 J.
