Hi everyone. I'm thinking about connect arduino to a 12 V DC battery car, but i have before to find out two things:- An electronic device, when it's connected to a battery, only gets the amp required or the battery gives more and the device breaks?
An electronic device, when it's connected to a battery, only gets the amp required or the battery gives more and the device breaks?
A voltage stabilizer is good or i need one with current limit?
Estaba hablando de que si da más amperaje del que el aparato electrónico soporta.
I = V / R, aplicando al circuito si la intensidad interna de la batería es baja, podrá dar más amperios.
If the current was controlled by the supply then each and every one of us would have a serious problem in our homes. The power company supplies MEGAWATTS and we use KILOWATTS, if the device using the power was not the limiting factor on our usage our houses would have all burned down yers ago.
Electronics are so expensive
QuoteElectronics are so expensiveNo, happily, they're about as ludicrously cheap as I can ever remember them.
Yeah, I bought 500 x zero-ohm resistors for $4.Can't do much better than that!
