Procedures : [a] Apparatus is set upRadas seperti dalam rajah disediakan
[b] Switch is on, rheostat is adjusted until ammeter shows a reading of 0.1 ASuis dihidupkan dan reostat dilaraskan sehingga bacaan ammeter pada 0.1 A
[c] The corresponding reading of voltmeter is taken and recordedBacaan voltmeter direkodkan dalam jadual
[d] The above steps are repeated for 4 values of current, 0.2 A, 0.3 A, 0.4A and 0.5ALangkah di atas diulang dengan menggunakan arus 0.2 A, 0.3 A, 0.4 Adan 0.5 A
[e] All ammeter and voltmeter readings are recorded in the tableKeseluruhan bacaan ammeter dan voltmeter direkodkan ke dalam jadual
[f] Graph V against I is plotted.Graf V melawan I diplotkan

Conclussion : When I increases , V decreases . that is I is inversely proportional to V.Hypothesis is acceptedApabila arus, I bertambah, beza keupayaan, V berkurang.

Discussions :
[a] Based on your graph, state the relationship between current and voltageBerdasarkan graf, nyatakan hubungan antara arus, I dengan beza keupayaan, V
When current increases , the voltage is decreases.Beza keupayaan, V berkurang secara seragam dengan arus, I
[b] From graph, calculate the gradient of the graph voltage, V against current, IDaripada graf, hitung kecerunan graf beza keupayaan, V melawan arus, l
using formula ;menggunakan rumus ;
Gradient = ( y2 y1) / ( x2 x1)= ( 1.5 - 0.5 ) / ( 0 0.5 )= - 1.2
[c] From graph, determine the voltage when current = 0.25 ADaripada graf, hitung nilai beza keupayaan apabila arus = 0.25 A
From graph, Daripada graf,
voltage = 1.2 V
http://nazuris.blogspot.com/ 5
voltage = 1.2 V
Precautionary : Make sure the wires are connected tightly.Pastikan wayar penyambung dipasang dengan kemas
Always switch off the current when the reading is not taken to avoid overheating. Of wires which lead to the increase in resistance.Pastikan suis sentiasa ditutup apabila tiada bacaan untuk mengelakkan panasyang boleh meningkatkan nilai rintangan dalam
Eye is perpendicular to the reading of voltmeter and ammeter to avoid parallax error.Kedudukan mata mesti bersudut tepat dengan skala bacaan untuk mengelakkan ralat paralaks
