a. Make a sketch homogeneous to that in Figure 8.3(a) but for an npn transistor instead of pnp.

b. The thinness of one of its three layers is what causes the BJT to manifest a high current reach. Identify that layer in Figure 8.3(a) as well-mannered-mannered as in your sketch for bisect (a) overhead. c. Briefly narrate the BJT’s influence as a switch.
