SET 12

A student carries out an experiment to investigate the relationship between base current,
Ib, and collector current, Ic, of a transistor.
The arrangement of the apparatus for the experiment is shown in Diagram 1.1.

Seorang pelajar menjalankan eksperimen untuk mengkaji hubungan antara arus tapak,
Ib, dan arus pengumpul, Ic, sebuah transistor.
Sususnan radas untuk eksperimen ditunjukkan dalam Rajah 1.1.

Diagram 1.1/ Rajah 1.1

The rheostat is adjusted until the milliammeter shows the corresponding reading, Ib, as
shown in Diagram 1.2.
The procedure is repeated with different values of Ib as shown in Diagrams 1.2, 1.3, 1.4,
1.5 and 1.6.

Reostat dilaraskan sehingga milliammeter menunjukkan bacaan Ib, seperti dalam Rajah
1.2.
Langkah di atas diulangi dengan nilai Ib yang berbeza seperti yang ditunjukkan dalam
Rajah 1.2, 1.3, 1.4, 1.5 dan 1.6.
