191 3.1KA3 1. Ic 62 KA3 VCE 9.1KA 0.68KA (a)
(a) Determine IC and VCE for the circuit (a) given below.
(b) Change β to 120 (50% increase), and determine the new values of IC and VCE for the
circuit of Figure (a)
(c) Determine the magnitude of the percent change in IC and VCE using the following
equations:
(d) Determine IC and VCE for the network of Figure (b).
(e) Change β to 180 and determine the new value of IC and VCE for the network of Figure (b)
(f) Determine the magnitude of the percent change in IC and VCE using the above equations.
(g) In each of the above, the magnitude of β was increased 50%. Compare the percent change in IC and VCE for each configuration, and comment on which seems to be less sensitive to changes in β.
