How much current can the Arduino handle?

Question

Arduino

There is a battery for 14v and 80 amps through the converter lowered from 14 to 5 volts.
And now I wonder if it is possible to connect a current of 80 amperes to Arduino or not. If not, please advise how to reduce current.

Answer 1

The device does not "withstand" the current, but "sweat" it. The battery current is how much energy it can give per unit of time. Key word can.

Answer 2

If you have a 14 volt battery 80 ampere * hours (and not amperes), then you can connect it through a 5 volt converter or even directly - (recommended arduino supply voltage 7-12, limit 6-20 V).
ps I would recommend refreshing your knowledge of electrical engineering, otherwise the arduino may not live long ...
