Just heard a YouTube science communicator (who should know better) say "higher voltage means you can get more current in the same cable" and felt my skin crawl for a second
#volt = difference in potential energy#current is the movement of the charge which is what the wire is actually facilitating#voltage is a difference a single point in a cable has no voltage thus the voltage is irrelevant for single points in a cable#w higher voltage u can get more *wattage* bc ur increasing voltage w the same current#watt=volt*amp#the voltage limitation for a single type of cable is also bc its a difference#its rating the max difference between a point in the wire & the environment/another point in the cable#current rating on a cable is meant to b independent of voltage so long as the voltage is within rating of the insulation#like obv it was probably a brain fart and he understood that but that should b one of those things where you immediately notice#(note - movement of charge is different than movement of electrons. electrons r fairly slow)#(and obv things like 'single points' are abstractions so theres nuance when you rly need to b precise#but for most nontechnical applications dw abt it)
