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.

4 Figure 4. 1 and Figure 4.2 show an assembly in a school hall. In Figure 4.1, a prefect discovered that a few rows of student could not hear the
principal’s voice clearly. .
When the two speakers are far apart as in Figure 4.2, the prefect found that more rows
of students could hear the principal’s voice clearly.
