Physics · Electromagnetic Induction
एक 2 H के प्रेरक (inductor) में धारा 3 A/s की निरंतर दर से परिवर्तित होती है। यदि प्रारंभिक धारा शून्य है, तो 4 सेकंड के बाद प्रेरक के सिरों पर वोल्टेज और उसमें संचित ऊर्जा का परिमाण क्रमशः होगा:
- 1VL = 6 V; WL = 144 J✓
- 2VL = 6 V; WL = 72 J
- 3VL = 1.5 V; WL = 144 J
- 4VL = 1.5 V; WL = 12 J
सही उत्तर देखें
VL = 6 V; WL = 144 J
