Thanks, I understand it a lot better now.
I'm still confused about how the two connect though...
For example, could you explain how something that charges a 2.5 ohm load @ 1W would charge a Li-ion battery (i.e. a phone?). Would it still be 1W considering how the iphone charger reacted or is...
I'm confused about the resistances of common electrical appliances. v=ir
So I was reading something about how fast iphones charge with different chargers and it got me thinking about the resistance of things like phone batteries.
So it said that it could charge at 5V and 2 amps, but also at 5V...
