Hi,
I'm learning the basics of EE, and I never fully understood voltage and current.
So, in a very simple circuit, if we increase voltage, the rate of elétrons will increase due to the increase of the force that "moves them" right? Then in the end, voltage's only purpous is to manipulate currents right?
( I don't know if my concepts are good, so please correct me in any way you like )
So why do electronic devices have labled a maximum voltage? I can supply 1000v to muito mobile phone with a 4000ohm resistance and I'll get 0,25A of supply, and that won't hurt it right? Cuz in the end the amount of eletrons passing through are the only thing that matters
I don't know, probably I'm wrong but please help me clarify
