With ideal conductor, ideal isolator and ideal source there is none of the losses. As soon as one of those is non-ideal, losses creep in. Your task when going passive is thus: make it ideal! Reduce resistance (wide tracks), increase isolation (large track-to-track distance, PCB with high isolation and low creepage), reduce current, reduce frequency. | |

| Jan 19, 2023 at 6:48 | comment | added | Curious Cosmopolitan | @datenheim! This is more of a theoritical question, just meant to ask, "How to maintain voltage at the far end in case of PCBs where voltage loss is obvious due to the tracks?" Rest are just the details to complete the question and avoid comments like there is no load. | |

You can drive quite alot of current through, say, an 18-gauge wire before the voltage loss becomes noticable. | |

| Jan 18, 2023 at 23:03 | comment | added | datenheim | Is this a theoretical or more practical question? | |
| Jan 18, 2023 at 22:41 | comment | added | Eugene Sh. | The voltage drop also depends on the current. Don't make long thin traces that are supposed to carry high currents. | |
