@6piz7wk:tchncs.de6piz7wkis there a way to calculate it?23:31:50
@6piz7wk:tchncs.de6piz7wki want to do prototype PCBs 23:31:59
@inv41idu53rn4m3:matrix.orginv41idu53rn4m3

Resistance is inversely proportional to cross-sectional surface area except not exactly but I don't know how the not exactly part works

@inv41idu53rn4m3:matrix.orginv41idu53rn4m3do some web searches :)23:34:48
@6piz7wk:tchncs.de6piz7wkbut i wanted to avoid doing that!23:35:32
@lispmacs:matrix.orglispmacsper the electronics textbook next to my bench, conductivity of a wire varies depending on type of material. Also, the longer the wire, the more resistance. Also, the greater the cross-sectional area of the wire, the less the resistance23:57:16
@lispmacs:matrix.orglispmacsalso, most types of wire have more resistance at warmer temperatures23:57:44

@6piz7wk:tchncs.de6piz7wkgreater the cross-sectional area of the wire the less the resistance?00:00:06
@lispmacs:matrix.orglispmacscorrect00:00:16
@6piz7wk:tchncs.de6piz7wkSo for prototyping i shouldn't have issues with using a thicker wire for traces?00:00:24
@6piz7wk:tchncs.de6piz7wk... as thicker is more managable by hand00:00:30
* @6piz7wk:tchncs.de6piz7wk wants to isolate the wires and lay them on a sticky surface 00:00:48
@lispmacs:matrix.orglispmacsthat is correct00:01:02
@6piz7wk:tchncs.de6piz7wkthanks00:03:17
@capt_hindsight:matrix.orgCaptHindsight 6piz7wk: thickness of the traces and their distance from one another and other layers also effects their impedance 00:27:16
