Detailed Solution
Download Solution PDFसंकल्पना:
- समांतर जोडणीतील रोध: जेव्हा दोन किंवा अधिक रोधांचे दोन बिंदू एकाच बिंदूंवर जोडलेले असतात आणि त्यांच्यातील विभवांतर समान असतो तेव्हा त्याला समांतर रोध म्हणतात.
समांतर जोडणीतील रोधाचा निव्वळ रोध/समतुल्य रोध (R) हा खालील सूत्राद्वारे दर्शविला जातो:
\(\frac{1}{R} = \frac{1}{{{R_1}}} + \frac{1}{{{R_2}}}\)
गणना:
दिलेले,
R1 = \(R\ Ω\)
R2 = \(20\ Ω\)
निव्वळ रोध/समतुल्य रोध (R) = 15 Ω
समांतर जोडणीतील रोधासाठी खालील सूत्र वापरू:
\({{1\over 15}={{1\over R}+{1\over 20}}}\)
\(5R=300\)
∴\(R=60\ Ω.\)
