Eksperimen (1) Hubungan antara rintangan dan luas keratan rentas dawai
Experiment Relationship between the resistance and the cross-sectional area of the wire

(2) Hubungan antara rintangan dan jenis dawai
Relationship between the resistance and the type of wire

Luas keratan rentas dawai mempengaruhi Jenis bahan dawai mempengaruhi rintangannya.
Inferens rintangannya. The type of material wire affect its resistance.
Inference Cross- sectional area of wire affect its resistance.

Apabila luas keratan rentas bertambah, rintangannya Apabila jenis bahan dawai berubah, rintangannya
Hipotesis berkurangan. turut berubah.
Hypothesis When the cross-sectional area of wire increases, its When the type of material of the wire changes, its
resistance decreases. resistance also changes.

Untuk mengkaji hubungan antara luas keratan rentas Untuk mengkaji hubungan antara jenis bahan dawai
Tujuan dawai dan rintangannya. dan rintangannya.
Aim To investigate the relationship between the cross-sectional To investigate the relationship between the type of
area of wire and its resistance. material of the wire and its resistance. UNIT 2
