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.

Guida passo passo

1. 1Series: R_total = R1 + R2 + R3 + ... (resistances add)
2. 2Parallel: 1/R_total = 1/R1 + 1/R2 + 1/R3 ... (reciprocals add)
3. 3Two resistors in parallel: R_total = (R1 × R2) / (R1 + R2)
4. 4Voltage divides in series; current divides in parallel
