allery200 V पर 60 W और 40 W रेटेड बल्ब 200 V में श्रृंखला में जुड़े हुए हैं। निरंतर प्रतिरोध मान लें. कौन सा बल्ब अधिक बिजली का उपयोग करता है, और कुल बिजली कितनी है?
A40 W बल्ब;
24 W
B60 W बल्ब;
24 W
C40 W बल्ब;
100 W
D60 W बल्ब;
100 W
Answer & Solution
Correct answer: A. 40 W बल्ब;
24 W
उनके प्रतिरोध 200²/60 और 200²/40 Ω हैं, इसलिए श्रृंखला शक्ति 24 W है और उच्च प्रतिरोध 40 W बल्ब अधिक उपयोग करता है।
