संकल्पना:

स्व:प्रेरकत्व:

  • स्व:-प्रेरकत्व धारावाही कुंडली का वह गुण है जो इसके माध्यम से प्रवाहित होने वाली धारा के परिवर्तन का प्रतिरोध या विरोध करता है।
  • यह मुख्य रूप से कुंडली में ही स्व-प्रेरित emf के कारण होता है।

F1 Madhuri Defence 20.12.2022 D9

  • स्व:-प्रेरकत्व, L = μr μ0 n2 A L
  • कुंडली में संग्रहीत ऊर्जा को\(E=\frac{1}{2}LI^2\) के रूप में दिया गया है जहाँ L = स्व:-प्रेरकत्व, I = परिपथ में प्रवाहित धारा

व्याख्या:

कुण्डली में संचित ऊर्जा \(\frac{1}{2}LI^2\) है
