alleryA 4 Ω ریزسٹر 6 Ω اور 3 Ω کے ایک متوازی جوڑے کے ساتھ 12 V میں سیریز میں ہے۔ 3 Ω ریزسٹر میں کل کرنٹ اور پاور تلاش کریں۔
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
متوازی مزاحمت 2 Ω ہے، جو مجموعی طور پر 2 A اور اس جوڑے میں 4 V دیتا ہے، لہذا 3 Ω ریزسٹر 4²/3 = 16/3 W کو ختم کر دیتا ہے۔
