  • mAh/g (milliamp-hours per gram) is essentially still a measurement of capacity, but in terms of current instead of power.

    We can do a little dimensional analysis here to translate between them. Power = Current x Voltage, so you’d multiply this (Current x Time)/(Weight) value by the nominal voltage of the cell to get to (Power x Time)/(Weight).

    Phone batteries are often specified in units of Current*Time (e.g. milliamp-hours), but I’m not completely sure why. I think it has to do with voltages being standardized for certain types of cells, so the only real variable in the battery capacity is the current.

    Edit: rearranged some ideas to make more sense






  • Yeah I’m not actually against marvel quips, though I definitely feel they became detrimental to the writing style of their films over time. When I complain about it, I’m really complaining about interruptions where they aren’t warranted and don’t contribute to the narrative.

    A good quip isn’t just funny- it can contribute to audience understanding, help with pacing, and fits naturally into the narrative. A bad quip interrupts the narrative for no reason other than to interrupt. I don’t really have a good example for this, it’s more of a ‘know it when you see it’ situation. It was definitely better in the early marvel films.

    As much as I love witty characters like Spider-Man, not everyone needs to be comic relief and sometimes it just doesn’t jibe with the story being told.
