(v) Procedure / Prosedur
1. The apparatus is arranged as shown in the diagram.
Radas disusun seperti ditunjukkan dalam rajah.
2. A 10 cm constantan wire is connected in the circuit.
Satu dawai konstantan 10 cm disambung dalam litar.
3. The rheostat is adjusted so that the voltmeter reading, V is 0.5 V.
Reostat diselaraskan supaya bacaan voltmeter, V ialah 0.5 V.
4. The reading of ammeter, I, is recorded.
Bacaan ammeter, I, direkodkan.
5. The experiment is repeated by adjusting the rheostat so that the voltmeter reading is 1.0 V,
1.5 V, 2.0 V and 2.5 V.
Eksperimen diulangi dengan menyelaras rheostat supaya bacaan voltmeter adalah 1.0 V,
1.5 V, 2.0 V dan 2.5 V.
6. The values of V and I are tabulated.
Nilai-nilai V dan I dijadualkan.
7. A graph of I against V is plotted.
Satu graf I melawan V diplotkan.
