Answer all questions in this sectio]n

The time suggested to complete this section is 60 minutes

1 A student carries out an experiment to find the relationship between base current , Ib , and

collector current , Ic, of a transistor. The arrangement of the apparatus for the experiment is shown in Figure 1.1

FIGURE 1.1

At the beginning of the experiment, a 2.2 kO resistor is used in the base circuit as shown in Figure 1.1. The switch is closed and the milliammeter reading Ib1, is recorded. The experiment is repeated to get a second reading, Ib2. The actual readings of Ib1 and Ib2 are shown in Figure 1.2 on page 6.

The experiment is repeated by using 3.9 kO , 4.7 kO , 6.8 kO and 10.1 kO resistors.

The readings of the milliammeter are shown in Figures 1.3, 1.4, 1.5 and 1.6 on page 6 and 7.
