Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFमालिका RLC परिपथात, प्रतिबाधा याद्वारे दिली जाते
\(Z = \sqrt {{R^2} + {{\left( {{X_L} - {X_C}} \right)}^2}}\)
अनुनादाच्या वेळी, प्रेरक अभिक्रियांचे परिमाण कॅपॅसिटिव्ह अभिक्रियाच्या परिमाणाइतकेच असते.
XL चे परिमाण = XC
या अटीवर, Z = R.
म्हणून अनुनादावर, प्रतिबाधा पूर्णपणे रोधक आहे आणि ती किमान आहे.
परिपथामधील विद्युतप्रवाह, I = V/Z
प्रतिबाधा कमीतकमी असल्याने विद्युतप्रवाह जास्तीत जास्त असतो.
प्रतिबाधा ही पूर्णपणे रोधक असल्याने शक्ती घटक म्हणजे ऐकल होय.
महत्त्वाचे मुद्दे:
- पूर्णपणे इंडक्टिव्ह परिपथामध्ये, विद्युतप्रवाह विद्युतदाबाला 90° ने मागे ठेवतो आणि पॉवर फॅक्टर शून्य मागे असते
- पूर्णपणे कॅपॅसिटिव्ह परिपथामध्ये, विद्युतप्रवाह विद्युतदाबाला 90° ने नेतो आणि पॉवर फॅक्टर शून्य अग्रगण्य असते
मालिका परिपथाच्या वारंवारता प्रतिसादाचे कथानक आकृतीत दाखविल्याप्रमाणे आहे:
