SET 10

A student carries out an experiment to investigate the relationship between the
temperature, q , and the electric current, I, flowing through a resistor. The arrangement of
the apparatus is as shown in Diagram 1.1.

Seorang pelajar menjalankan eksperimen untuk mengkaji hubungan antara suhu, q,
dengan arus elektrik, I, yang mengalir melalui suatu perintang. Susunan radas
ditunjukkan dalam Rajah 1.1.

Diagram 1.1/ Rajah 1.1

The switch is turned on and the ammeter reading is recorded when the temperature of
water, q = 10 C. The water is then heated slowly and the ammeter reading is recorded
o
o
after every temperature rise of 10 C. The corresponding ammeter readings, I, for each
temperature, q , are shown in Diagrams 1.2, 1.3, 1.4, 1.5 and 1.6.

Suis dihidupkan dan bacaan ammeter dicatat apabila suhu air, q = 10 C. Kemudian, air
o
dipanaskan secara perlahan-lahan dan bacaan ammeter dicatat selepas setiap kenaikan
o
suhu sebanyak 10 C. Bacaan ammeter, I, yang sepadan untuk setiap suhu, q,
ditunjukkan pada Rajah 1.2, 1.3, 1.4, 1.5 dan 1.6.
