在電路中,有幾個燈泡,及電池
全部燈泡+電池也是相同
一個是以「串聯」來接駁...
一個是以「並聯」來接駁(全部燈泡也是)
請問那一個種方法 燈泡會較暗?
如果條問題是這樣 應該點樣清楚地答好?
雖然我明白點解- - 但我唔知點樣表達得清楚!
希望答案唔好太過難...我得中二炸!!!
關於中二級--科學問題!

✔ 最佳答案
The brightness of each light bulb depends on the voltage across it. The higher the voltage, the brighter is the bulb.In a parallel connection (並聯), each bulb shares all the voltage of the battery.
In a series connection (串聯), each bulb only share a fraction of the voltage of the battery.
Hence, bulbs connected in parallel are brighter than those connected in series.

在這情況下,,
並聯是會較暗~
並聯電流 :
I=I1+I2+I3+I4....
即每個負載的電流的總和=電路總電流
故並聯是分薄了電流,,
但串聯電流 :
I=I1=I2=I3=I4....
即每個負載的電流=電路總電流
故任何一處的電流是相等的,,
