संकल्पना:

प्रेरण प्ररोध:

प्रेरण प्ररोध (XL) याद्वारे दिला जातो:

XL = ωL

ω = रेडियन/सेकंद मध्ये वारंवारता जी खालीलप्रमाणे लिहिली जाऊ शकते:

ω = 2πf

XL = ωL = 2πfL

जेथे, 

f  = Hz मध्ये वारंवारता

L = हेन्रीमधील प्रेरित्राचे मूल्य

वरीलवरून, आपण असा निष्कर्ष काढतो की:

XL ∝ f (स्थिर L साठी)

प्रेरण प्ररोध वारंवारतेच्या थेट प्रमाणात असतो.

धारणी अवरोधन​:

धारणी अवरोधन याद्वारे दिले जाते:

\({X_C} = \frac{1}{{ω C}}\)

जेथे ω = 2πf

\({X_C} = \frac{1}{{2π fC}}\)

\({X_C} \propto \frac{1}{{ f}}\)

धारणी अवरोधन वारंवारतेच्या व्यस्त प्रमाणात असते.

जेथे, C = धारिता मूल्य फॅराडमध्ये

गणना:

दिलेल्याप्रमाणे, धारिता (C) = 1 μF

वारंवारता (f) = 50 Hz 

धारणी अवरोधन\({X_C} = \frac{1}{{2π \times 50\times 1\times 10^{-6}}}\) 

XC = 3183.09 Ω
