1. A student carries out an experiment to investigate the relationship between the length of wire ,l, and

the resistance ,R. The arrangement of apparatus is shown in Diagram 1.1. An ammeter , dry cells, a

rheostat, a switch and a piece of constantan wire are connected in series. A voltmeter is used to

measure the potential difference, V, across the wire of length , l.

Seorang murid menjalankan satu eksperimen untuk mengkaji hubungan antara panjang suatu

dawai, l, dengan rintangan , R. Susunan radas ditunjukkan dalam Rajah 1.1 . Sebuah ammeter, sel

kering, reostat, suis dan dawai konstantan disambung secara sesiri. Sebuah voltmeter digunakan

untuk mengukur beza keupayaan , V , merentasi dawai sepanjang , l .

Diagram 1.1

Rajah 1.1

A constantan wire of length , l = 20.0 cm is set up by moving the jockey on the wire which is

attached to the meter ruler. When the switch is on, the rheostat is adjusted until the ammeter reading

is 1.0 A. The voltmeter reading is as shown in Diagram 1.2.

Dawai konstantan dengan panjang, l = 20.0 cm disediakan dengan menekan joki di atas dawai yang

dilekatkan pada pembaris meter. Apabila suis dihidupkan , reostat dilaraskan sehingga bacaan

ammeter adalah 1.0 A. Bacaan voltmeter, V , adalah sebagaimana ditunjukkan dalam Rajah 1.2.

Procedure of experiment

State how to control the manipulated variable

The measuring cylinder is filled with water of volume,

V = 250 ml and mixed with salt of mass 10 g.

Immersed the thistle funnel into the water at the depth of

water, h = 30 cm .

State how to measure the responding variable

Measure the diffrence length of mercury column, y , at the

manometer and record the data.

Repeat the experiment

Repeat the experiment with different mass of salt m = 20g ,

30g, 40g and 50g.

4. Inference:

The output voltage of the transformer depends on the number

of turns of the secondary coil.

1

1

Hypothesis:

The output voltage of the transformer increases as the

number of turns of the secondary coil increases

1 1

Aim of the experiment :

To investigate the relationship between the number of turns

of the secondary coil and output voltage of a transformer.

Variables in the experiment:

Manipulated variable: the number of turns of the secondary

coil, N

Responding variable: The output voltage, V

Fixed variable: number of turns of the primary coil and the

input voltage.
