alleryA 4 Ω ਰੋਧਕ 12 V ਦੇ ਪਾਰ 6 Ω ਅਤੇ 3 Ω ਦੇ ਸਮਾਨਾਂਤਰ ਜੋੜੇ ਦੇ ਨਾਲ ਲੜੀ ਵਿੱਚ ਹੈ। 3 Ω ਰੋਧਕ ਵਿੱਚ ਕੁੱਲ ਕਰੰਟ ਅਤੇ ਪਾਵਰ ਲੱਭੋ।
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
ਸਮਾਨਾਂਤਰ ਪ੍ਰਤੀਰੋਧ 2 Ω ਹੈ, ਜੋ 2 A ਨੂੰ ਸਮੁੱਚਾ ਅਤੇ ਉਸ ਜੋੜੇ ਵਿੱਚ 4 V ਦਿੰਦਾ ਹੈ, ਇਸਲਈ 3 Ω ਰੋਧਕ 4²/3 = 16/3 W ਨੂੰ ਵਿਗਾੜਦਾ ਹੈ।
