alleryদুটা 12 Ω ৰেজিষ্টৰ 12 V ৰ ওপৰেৰে চলে: প্ৰথমে 1 মিনিটৰ বাবে শৃংখলাবদ্ধভাৱে, তাৰ পিছত 1 মিনিটৰ বাবে সমান্তৰালভাৱে। মুঠ শক্তি কিমান ব্যৱহাৰ কৰা হয়?
A1800 J
B1080 J
C720 J
D1440 J
Answer & Solution
Correct answer: A. 1800 J
শৃংখলা পৰ্যায়ত (12²/24) × 60 = 360 J ব্যৱহাৰ কৰা হয় আৰু সমান্তৰাল পৰ্যায়ত (12²/6) × 60 = 1440 J, মুঠ 1800 J।
