A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
Pin pitch means how tiny the physical pins in the connector can be spaced apart.
IR drop losses happen because a wire has resistance, it isn't a perfect conductor. 28AWG wire has about 0.22ohm/m. Given a 2 meter cable, you might expect to see 0.44ohm one-way. Current is also travelling back, so the circuit "sees" another 0.44ohm. That's a total of 0.88ohm
A wire will cause voltage drop following ohm's law. V=I/*R. So for 1A of current, you will see 0.88V lost.
Say you're trying to charge at 15W (5V 3A), your phone is only going to 'see' 2.36 volts, and 7.9W are wasted in the cable.
For a 100W device (20V, 5A), 4.4V are lost, also meaning 22W are wasted.
(For others reading this, this is a perfect followup to my comment here explaining the "why", while this is an excellent view into the "how" and picks up the bits I dropped about Ohms Law.)
