Question

In the circuit shown in the figure, the input voltage V i is 20 V , V B E = 0 and V C E = 0 . The values of I B , I C and β are given by, I B = 20 μA , I C = 5 mA , β = 250, I B = 25 μA , I C = 5 mA , β = 200, I B = 40 μA , I C = 10 mA , β = 250, I B = 40 μA , I C = 5 mA , β = 125

MARKS App · Accepted Answer

V i = I B R B + V B E (By Kirchoff's Voltage Law) 20 = I B × 500 × 10 3 + 0 I B = 20 500 × 10 3 = 40 μA V C C = I C R C + V C E (By Kirchoff's Voltage Law) 20 = I C × 4 × 10 3 + 0 I C = 5 × 10 - 3 = 5 mA β = I C I B = 5 × 10 - 3 40 × 10 - 6 = 125
