NEET · Physics · STD 12 - 14. Semicondutor electronics

दिए गए परिपथ आरेख में, निवेश वोल्टता \(\left( V _{ i }\right) 20 V\), \(V _{ BE }=0\) तथा \(V _{ CE }=0\) है । \(I _{ B }, I _{ C }\) और \(\beta\) के मान होंगे

  1. A \(I_B=40\)\(\mu A\), \(I_C=10mA\),\(\;\;\beta \)\(=250\)
  2. B \(I_B=25\)\(\mu A\), \(I_C= 5 mA,\)\(\;\;\beta \)\(=200\)
  3. C \(I_B=40\)\(\mu A\), \(I_C = 5mA\),\(\;\;\beta \)\(= 125\)
  4. D \(I_B=20\)\(\mu A\),\( I_C = 5mA\),\(\;\;\beta \)\(=250\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(I_B=40\)\(\mu A\), \(I_C = 5mA\),\(\;\;\beta \)\(= 125\)

Step-by-step Solution

Detailed explanation

Given \(V_{B E}=0\) ;  \(V_{C E}=0\) \(\therefore \quad\) Collector current, \(I_{C}=\frac{(20-0)}{4 \times 10^{3}}\)
