NEET · Physics · STD 12 - 14. Semicondutor electronics

એક આકૃતિમાં દર્શાવેલ પરિપથમાં ઇનપુટ વોલ્ટેજ \(V_i =20V, V_{BE}=0 \) અને \(V_{CE}=0\) છે. \(I_B,I_c\) અને \(\beta \) ના મૂલ્યો આપવામાં આવે છે.

  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 \(I_B=20\) \(\mu A\), \( I_C = 5\,mA\), \(\;\;\beta \) \(=250\)
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, \(I_{C}=\frac{(20-0)}{4 \times 10^{3}}\)
