allery200 V ରେ 60 W ଓ 40 W ନିର୍ଦ୍ଧାରିତ ବଲ୍ବକୁ 200 V ଉତ୍ସରେ ଶ୍ରେଣୀକ୍ରମରେ ଯୋଡ଼ାଯାଏ। ପ୍ରତିରୋଧ ସ୍ଥିର ବୋଲି ଧରନ୍ତୁ। କେଉଁ ବଲ୍ବ ଅଧିକ କ୍ଷମତା ବ୍ୟୟ କରେ ଏବଂ ମୋଟ କ୍ଷମତା କେତେ?
A40 W ବଲ୍ବ;
24 W |
B60 W ବଲ୍ବ;
24 W |
C40 W ବଲ୍ବ;
100 W |
D60 W ବଲ୍ବ;
100 W |
Answer & Solution
Correct answer: A. 40 W ବଲ୍ବ;
24 W |
ସେମାନଙ୍କର ପ୍ରତିରୋଧଗୁଡିକ 200² / 60 ଏବଂ 200² / 40 are, ତେଣୁ ସିରିଜ୍ ଶକ୍ତି ହେଉଛି 24 W ଏବଂ ଉଚ୍ଚ-ପ୍ରତିରୋଧ 40 W ବଲ୍ବ ଅଧିକ ବ୍ୟବହାର କରେ |
