B. Collector Feedback Biasing a Transistor: 1. Construct the circuit using resistor Rc = 470 2 and a potentiometer Rg =470 k2 shown in Fig. 2. Adjust voltage Vcc to 15 V. 2. Adjust the potentiometer mechanism until voltage value of Vc equal to 7V, then measure value of the potentiometer and record this value. 3. Measure passing currents from collector and base and record in Table 1. or measure VRc then calculate by following formula: VRC Ic Rc 4. Draw the load line making necessary calculations and show the operating (Q) point. 5. Use a transistor with a different value of ß, repeat step 3 and record measured values in Table 1.
