In terms of V, R1, R2, R3, R4,
a) Find the current through resister R1 (resistance = R1).
b) Find the current through resister R2 (resistance = R2).
c) Find the current through resister R3 (resistance = R3).
d) Find the current through resister R4 (resistance = R4).

Thanks a lot~

✔ 最佳答案
因爲你淨係要方程式,無需要數字,如果你有比數字,我可以幫你計,如果你要我幫你計,[email protected]
方程式如下 :
第一步
先將R1同R2以並聯方式加起來=Ra
再將R3同R4以並聯方式加起來=Rb
接下來將Ra同Rb以串聯方式加起來=R
最後,I=V/R
第二步
先計出Ra同Rb既電壓Va & Vb,( Va = I x Ra )& ( Vb = I x Rb)。
I(R1) = Va / R1
I(R2) = Va / R2
I(R3) = Vb / R3
I(R4) = Vb / R4



希望幫到你
