Second Evaluation

No. 1 If the base resistor is very small, -the -transistor will operate in the a. cutoff region b. active region c. saturation region d. breakdown region

No. 2 If a transistor operates in the middle of the load line, an increase in the base resistance will move the Q-point a. up b. down c. nowhere d. off the load line

No. 3 The saturation point is approximately the same as a. cutoff point b. lower end of the load line c. upper end of the load line

No. 4 When the collector resistance decrease in a base biased circuit, the load line becomes a. more horizontal b. more vertical c. fixed

No. 5 The first step in analyzing emitter biased circuits is to find the a. base current b. emitter voltage c. emitter current d. collector current

No. 6 If the emitter resistance decreases, the collector voltage a. decreases b. stays the same c. increases d. breaks down the transistor

No. 7 If the emitter resistance doubles in a VDB circuit, the collector current will a. double b. drop in half c. remain the same d. increase

No. 8

a) What is the emitter voltage?

b) The collector voltage?

c) Draw the load line, plot the Q-point!

d) Redesign the circuit to get the Q-point in the middle of the load line.

Given: R1 = 12KW, R2 = 3KW, RC = 3.2 KW, RE = 1KW, VCE = 10V
