材料(Materials):
1.5V battery x (from 2 to 5)
LED x 1
電路(Circuit):
上圖右方是LED正極的電壓;上圖左方是LED負極的電壓。
The right side is the voltage applied to LED anode. The left side is the voltage applied to LED cathode.
我們可以做底下的實驗(The Experiments):
- 讓正負極的電壓相同。(The voltage between anode and cathode is equal.)
- 讓正極的電壓大於負極。(The anode voltage is higher than the cathode voltage.)
- 讓正極的電壓小於負極。(The anode voltage is lower than the cathode voltage.)
進行實驗時,請觀察LED的亮度與正負極電壓之間的關係。
Please observe the relationship between the voltage and LED brightness during the experiment.
