Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसमानांतर अनुनादी परिपथ में, प्रेरणिक प्रतिघात (XL) धारिता प्रतिघात (XC) के बराबर है। यह परिपथ शुद्ध प्रतिरोधक बन जाता है।
अनुनाद पर, XL = XC
समानांतर अनुनाद पर, प्रतिबाधा अधिकतम हो जाती है।
समानांतर अनुनाद पर लाइन धारा Ir = IL cos ϕ
\(\frac{V}{{{Z_r}}} = \frac{V}{{{Z_1}}}X\frac{R}{{{Z_1}}}or\frac{1}{{{Z_r}}} = \frac{R}{{Z_L^2}}\;\)
\(\frac{1}{{{Z_r}}} = \frac{{\frac{R}{L}}}{C} = \frac{{CR}}{L}\left( {as\;Z_L^2 = \frac{L}{C}} \right)\)
इसलिए, परिपथ प्रतिबाधा इस प्रकार दी जाएगी
\({Z_r} = \frac{L}{{CR}}\)
