NEET 2018 Physics Common Emitter Configuration MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In the circuit shown in the figure, the input voltage Vᵢ is 20 V, V_BE = 0 and V_CE = 0. The values of I_B, I_C and β are given by
A
I_B = 40 μA, I_C = 10 mA, β = 250
B
I_B = 25 μA, I_C = 5 mA, β = 200
C
I_B = 20 μA, I_C = 5 mA, β = 250
D
I_B = 40 μA, I_C = 5 mA, β = 125
Correct Answer
Option A
Detailed Explanation
Using the relation I_C = βI_B, we can calculate I_C for each option and match it with the given β value. Option A satisfies the condition.
