alleryA 4 Ω রোধ 6 Ω এবং 3 Ω 12 V জুড়ে সমান্তরাল জোড়া সহ সিরিজে রয়েছে। 3 Ω রোধে মোট বর্তমান এবং শক্তি খুঁজুন।
A2 A; 12 W
B4 A; 48 W
C2 A; 16/3 W
D2 A; 48 W
Answer & Solution
Correct answer: C. 2 A; 16/3 W
সমান্তরাল রোধ হল 2 Ω, সামগ্রিকভাবে 2 A দেয় এবং সেই জোড়া জুড়ে 4 V দেয়, তাই 3 Ω রোধ 4²/3 = 16/3 W বিলুপ্ত করে।
