a. Determine IC and VCE for the network of Fig. 4.108.
In Figure 4.108

b. Change β to 135 and determine the new value of IC and VCE for the network of Fig. 4.108.
c. Determine the magnitude of the percentage change in lC and VCE using the following equations:

d. Determine IC and VCE for the network of Fig. 4.112.
