alleryਦੋ 12 Ω ਰੋਧਕ 12 V ਵਿੱਚ ਚੱਲਦੇ ਹਨ: ਪਹਿਲਾਂ 1 ਮਿੰਟ ਲਈ ਲੜੀ ਵਿੱਚ, ਫਿਰ 1 ਮਿੰਟ ਲਈ ਸਮਾਨਾਂਤਰ ਵਿੱਚ। ਕਿਹੜੀ ਕੁੱਲ ਊਰਜਾ ਵਰਤੀ ਜਾਂਦੀ ਹੈ?
A1800 J
B1080 J
C720 J
D1440 J
Answer & Solution
Correct answer: A. 1800 J
ਲੜੀਵਾਰ ਪੜਾਅ (12²/24) × 60 = 360 J ਅਤੇ ਪੈਰਲਲ ਪੜਾਅ (12²/6) × 60 = 1440 J, ਕੁੱਲ 1800 J ਦੀ ਵਰਤੋਂ ਕਰਦਾ ਹੈ।
