In the circuit shown in the figure, the input voltage \(V_i\) is \(20\,\, V, \,\,V_{BE} = 0 \) and \(V_{CE}= 0.\) The values of \(I_B\,,\,I_c\) and \(\beta\) are given by
- A \(I_B=40\)\(\mu A\), \(I_C=10mA\),\(\;\;\beta \)\(=250\)
- B \(I_B=25\)\(\mu A\), \(I_C= 5 mA,\)\(\;\;\beta \)\(=200\)
- C \(I_B=40\)\(\mu A\), \(I_C = 5mA\),\(\;\;\beta \)\(= 125\)
- D \(I_B=20\)\(\mu A\),\( I_C = 5mA\),\(\;\;\beta \)\(=250\)
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, \(I_{C}=\frac{(20-0)}{4 \times 10^{3}}\)
