I have a simple question about watts...
So if I had a laptop that charged with a 60 watt power supply, could I:
-Charge it with 10 amps at 6 volts? (that is the same as 60 watts)
-Charge it with 6 amps at 10 volts? (that is ALSO the same as 60 watts)
-Charge it with 5 amps at 12 volts? (that is ALSO the same as 60 watts)
Watts is just how much 'energy' passes a single point every second (or whatever), so it doesn't matter how you get the watts, watts is still watts?
I'm still trying to grasp the whole concept of watts, so yours answers are infinitely appreciated!!!
