Bipolar Junction Transistor

Usually, the range of Beta(β) is (Answer in _ to _ )

Given an α_dc of 0.998, determine

I_C if I_E=4mA. (Answer must be in 3 decimal places)

Due to flow of free electrons from emitter to base

Given that α_dc = 0.980, determine

the value of β_dc.

Practical value of α is less than unity, but in the range of ( _ to _ )

Determine α_dc if I_E = 2.8mA and I_B=20uA.( Answer must be in 3 decimal places)

Given that β_dc =120, determine the

corresponding value of α_{dc .} ( Answer must be in 3 decimal places)

Two kinds of BJT sandwiches

Find IE if IB = 40uA and α_dc is 0.98.

Given that β_dc = 120 and I_C = 2.0 mA, find I_E and I_B.(Answer must be in

whole number)
