allery200 V वर 60 W आणि 40 W रेट केलेले बल्ब 200 V मध्ये मालिकेत जोडलेले आहेत. सतत प्रतिकार गृहीत धरा. कोणता बल्ब जास्त पॉवर वापरतो आणि एकूण पॉवर म्हणजे काय?
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
त्यांचे प्रतिकार 200²/60 आणि 200²/40 Ω आहेत, त्यामुळे मालिका शक्ती 24 W आहे आणि उच्च-प्रतिरोधक 40 W बल्ब अधिक वापरतो.
