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.
1 1
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.
