धारणा:

एक ट्रांजिस्टर के लिए आधार धारा, उत्सर्जक धारा और संग्राहक धारा निम्नानुसार हैं:

IE = IB + IC

जहाँ IC = αIE

α = ट्रांजिस्टर का धारा लाभ

गणना:

दिया गया है कि,

IC = 0.95 mA

IB = 0.05 mA

∴ IE = IB + I= 0.05 + 0.95 = 1 mA

उपरोक्त अवधारणा से,

IC = αIE

\(\alpha=\frac{I_C}{I_E}=\frac{0.95}{1}=0.95\)
