Important Points
और उभयनिष्ठ आधार DC धारा लाभ (α) ट्रांजिस्टर के संग्राहक धारा और ट्रांजिस्टर के एमिटर धारा का अनुपात होता है, अर्थात्
\(α = \frac{{{I_C}}}{{{I_E}}}\)
ट्रांजिस्टर धारा निम्न संबंध द्वारा संबंधित हैं:
IE = IB + IC
अब α को निम्न रूप में लिखा जा सकता है:
\(α = \frac{{{I_C}}}{{{I_B+I_C}}}\)
अंश और हर दोनों को IB से विभाजित करने पर, हमें निम्न प्राप्त होता है:
\(α = \frac{{{I_C/I_B}}}{{{1+I_C/I_B}}}\)
चूँकि \(β = \frac{{{I_C}}}{{{I_B}}}\)
\(α = \frac{β }{{β + 1}}\) 'या'
\(β = \frac{α }{{1-α}}\)
