How to Connect Resistors in Series and Parallel

Last Updated on September 26, 2025 by Swagatam 36 Comments

combining resistors in series and parallel

There are three ways to interconnect resistors: series, parallel and in combination of series/parallel. When resistors are joined in series, the current passing via one resistor also passes through the next. When resistors are joined in parallel, they are wired across each other, resulting in the same voltage across each resistor. When resistors are connected […]
