Resistors can be connected in series (end-to-end, increasing total resistance) or parallel (side-by-side, decreasing total resistance). Understanding these configurations is fundamental to circuit analysis and electronics design.
ステップバイステップガイド
- 1Series: R_total = R1 + R2 + R3 + ... (resistances add)
- 2Parallel: 1/R_total = 1/R1 + 1/R2 + 1/R3 ... (reciprocals add)
- 3Two resistors in parallel: R_total = (R1 × R2) / (R1 + R2)
- 4Voltage divides in series; current divides in parallel
解いた例
入力
100Ω and 100Ω in parallel
結果
50Ω total
(100×100)/(100+100) = 50
入力
100Ω and 100Ω in series
結果
200Ω total
Simple addition
