alleryరెండు 12 Ω రెసిస్టర్లు 12 V అంతటా నడుస్తాయి: మొదట సిరీస్లో 1 నిమి, తర్వాత సమాంతరంగా 1 నిమి. మొత్తం శక్తి ఎంత ఉపయోగించబడుతుంది?
A1800 J
B1080 J
C720 J
D1440 J
Answer & Solution
Correct answer: A. 1800 J
సిరీస్ దశలో (12²/24) × 60 = 360 J మరియు సమాంతర దశ ఉపయోగాలు (12²/6) × 60 = 1440 J, మొత్తం 1800 J.
