We wish to design the circuit shown below for a collector current of 2,4 mA. Answer the following questions and choose only one answer for each question.
- Compute the base current IB .
- Compute the required value of base potential, VB. Assume that IE=IC .
- Compute the required value of R2 such that this resistor carry a current equal to 19 times of IB. Assume that the base current IB can be negligible in the calculation of base potential.
- Calculate the output impedance Rout for the circuit shown in figure. Assume VA = ∞.
