Key Points
కాన్సెప్ట్:
శ్రేణిలో సంకలనం \(R_{eq}\) = R1 + R2 + R3.
సమాంతరంలో సంకలనం \(\frac{1}{{{R_{eq}}}} = \frac{1}{{{R_1}}} + \frac{1}{{{R_2}}} + \frac{ 1}{{{R_3}}}\) .
సాధన :
4 నిరోధకతలను సమాంతరంగా అనుసంధానం చేయనివ్వండి.
R 1 = 2 \(\Omega\) , R 2 = 4 \(\Omega\) , R 3 = 5 \(\Omega\) , R 4 = 20 \(\Omega\) .
\(\frac{1}{{{R_{eq}}}} = \frac{1}{{{R_1}}} + \frac{1}{{{R_2}}} + \frac{1}{{{R_3}}} + \frac{1}{{{R_4}}}\)
R1||R2 కోసం
\(\frac{1}{{{R_{eq_1}}}} = \frac{1}{{{2}}} + \frac{1}{{{4}}} \) = \(\frac {4}{3}\) \(\Omega\)
R2 ||R3 కోసం
\(\frac{1}{{{R_{eq_2}}}} = \frac{1}{{{5}}} + \frac{1}{{{20}}} \) = 4 \(\Omega\) ,
Req1 ||Req2
\(\frac{1}{R_{eq}} = \frac{\frac{4}{3}\times4}{\frac{4}{3} +4} \) = 1 \(\Omega\) .
అందువల్ల \({R_{eq}} = 1 \Omega\)
ఇది \(2 \Omega\) విద్యుత్ వలయం యొక్క అతి చిన్న నిరోధకత కంటే తక్కువగా ఉంటుంది
