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

              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.
