एक उभयनिष्ठ उत्सर्जक अभिविन्यास के लिए धारा प्रवर्धक गुणक 59 है। यदि उत्सर्जक धारा 5 mA है, तो संग्राहक धारा का मान है :


Options:

  1. 4.92 mA
  2. 0.984 mA
  3. 1.02 mA
  4. 5.08 mA

Right Answer: 4.92 mA

उभयनिष्ठ उत्सर्जक (Common Emitter) के लिए धारा प्रवर्धक गुणक β = 59 दिया गया है। हम जानते हैं कि α = β/(1+β) = 59/60 होता है। साथ ही, α = I_c/I_e (जहाँ I_c संग्राहक धारा और I_e उत्सर्जक धारा है)। I_c = α × I_e = (59/60) × 5 = 295/60 = 4.916 mA, जो लगभग 4.92 mA है।
