Okay, the situation is we’re gonna go charge a battery at different voltage and of course at different currents. Now I want to know if there’s a relation or some sort of a formula, I just want to confirm the results, thanks.

This is a weird question but… I was getting a jump on my car today and we accidentally messed up the jumper cables and the electricity was just flying. Out of morbid curiosity, if you were stupid enough to grab both ends of the cable, is the charge of a car battery enough to fatally [...]
