re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@s0 @starkatt @LexYeen uhg okay getting overwhelmed again, let me see if i follow so far

voltage is just how different the positive/negative ends are so it's how violent the reaction is

amperage is the "volume" of electricity that you get by calculating voltage and resistance i guess??? and amp-hours are like "if you discharged this whole battery in one hour, it'd be this many amps"

watts are uhhhhhh

re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@kat @s0 @LexYeen yeah exactly!

re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@starkatt @s0 @LexYeen okay cool everything i find describes amps as like a totally separate thing from voltage so knowing one's a function of the other helps a lot, phew

re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@starkatt @s0 @LexYeen except amps being a function of volts makes it seem weird that watts are a function of amps and volts

nvm i'm lost again

re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@kat @starkatt @LexYeen current is a function of voltage *and other things*; 5 V across a 5 Ω resistor gives you 1 A, and consequently 5 W of heat being produced in the resistor, but 5 V across a 10 Ω resistor gives you 0.5 A, and consequently 2.5 W of heat

@starkatt @s0 @Felthry @LexYeen

following so far, i'm just not really sure what different thing amps and watts are measuring if amps are already a product of voltage/resistance

like i guess by the time you get to watts you've multiplied by voltage twice??? i'm not sure why really

re: parts suggestion specifically about batteries re: longish, about batteries and LEDs 

@kat @starkatt @LexYeen yes, power is proportional to voltage squared (in a resistive medium)

@kat @starkatt @LexYeen also i think this thread keeps breaking because this s0 person is on an instance that isn't on awoo's allow list, sorry about that
