But if you don't like putting resistors in parallel, go ahead and put them in a series, and then compute the electrical conductance of the pair: 10 S "+" 10 S = 5 S ("S" is Siemens) > and if you asked me (ie a layman) to "add two resistors together", i sure as hell wouldn't wire them in parallel lol Maybe that's the reason why people don't ask you to fix their wiring or to design their schematics for them? Parallel impedances are just as ubiquitous and important as serial ones.
