6.10 Heat and current (SPM 2007) Arus dan Pemanasan
Inference / Inferens: The temperature depends on current
Arus mempengaruhi suhu
Hypothesis / Hipotesis: The higher the current, the higher the temperature.
Semakin tinggi arus, semakin tinggi suhu
Aim / Tujuan eksperimen: To investigate the relationship between the current and
temperature
Untuk mengkaji hubungan antara arus dan suhu
Variables/ Manipulated/dimanipulasi : current/ arus, I
Pembolehubah: Responding / bergerak balas: : temperature/ suhu, T
Fixed/ Malar : : time of heating /masa pemanasan
Apparatus / Radas dan bahan: Thermometer, power supply, water, stopwatch, ammeter, heater
termometer, bekalan kuasa, air, jam randik, ammeter, pemanas,
reostat
Arrangement of apparatus /
Susunan radas:
Procedure / Prosedur : • Adjust the rheostat so the ammeter reading I = 0.5 A.
• Measure the water temperature
• Repeat the experiment with the current, I = 1.0 A, 1.5 A, 2.0
A and 2.5 A.
• Laraskan rheostat sehingga bacaan ammeter I = 0.5 A
• Ukur suhu air
• Ulang eksperimen dengan arus, I = 1.0 A, 1.5 A, 2.0 A and 2.5 A.
