AIM: To obtain the common emitter output characteristics of a bipolar junction transistor.

                                    Figure  2

1. Connect the circuit as shown in Figure 2.
2. Ask the Supervisor to check the circuit connection.
3. Copy Table 2 into your answer booklet.

Table 2

VCE (V	1	2	4	6	8
Ic (mA)

 

 

 

4.  Close switches SW1 and SW2.
5.  Set Ib to 10 µA by varying V1.
6.  Adjust Vcc until the voltmeter (VCE) reads 1 V.
7.  Read and record in Table 2 the corresponding value of Ic.
8.  Repeat steps (f) and (g) for the other values of VCE in Table 2.
9. Plot a graph of Ic (mA) on the vertical axis against V­CE (V) on the horizontal axis.
10. From the graph drawn in (i), determine the
    1. saturation point of the transistor;
    2. Active region of the transistor.
