Detailed Solution
Download Solution PDFअवधारणा :
एक ट्रांजिस्टर के लिए आधार धारा, उत्सर्जक धारा और संग्राहक धारा संबंधित हैं:
IE = IB + IC
जहाँ IC = βdc IB
βdc = ट्रांजिस्टर का धारा लाभ जिसे इस प्रकार परिभाषित किया गया है:
\(β=\frac{I_C}{I_B}\)
β संग्राहक में गुजरने वाले उत्सर्जक धारा का अंश है।
गणना :
माना कि उत्सर्जक धारा IE है।
चूंकि आधार पुनर्संयोजन में उत्सर्जित धारा वाहकों का 1% खो जाता है, संग्राहक धारा उत्सर्जक धारा का 99% होगी यानी
IC = 0.99 IE
और आधार धारा 1% यानी 0.01 IE होगी
∴ β निम्न होगा:
\(β=\frac{I_C}{I_B}=\frac{0.99I_E}{0.01I_E}\)
β = 99
