I don’t want this too be too late so just gonna throw this up rn and edit it later with my notes later so look forward to learning about capacitors :)

Fuck it we ball, capacitors what I know of them is they help motors start. In HVAC we got two of them run capacitor a and start capacitors. Motors that are aren’t 3 phase need a phase shift to get them going. Thing is motors need power coming in to be just right if a start capacitor is left running it will draw locked motor amperage and shut it all down so it’s put in series with a PTC relay (once this gets too hot it opens and shuts off power to the start capacitor) letting just the run to do it’s thing.

Capacitors need to be tested by isolating and discarding them and checking for capacitance in microfarads. The rating is usually on the capacitor and needs to be within ±10%. On the capacitor the voltage is supplied too with 2 different values. The higher value is the real one so this means you can use it on a size lower if you want. I’ve heard of testing them under load to fully get how they work,you take amperage on the start winding then multiply by 2652 then divide voltage across the capacitor to check if it’s good.

Anyway capacitors got oil in them to dissipate heat, thin plates of metal and plastic between them to insulate. These are used to store power, try not to fuck with them even unplugged they can still hurt you. The oil can also be an issue obvs. Anyway they store and discharge voltage they don’t boost it, at least in ac systems. If you read a higher voltage it’s most likely back EMF generated from the motor as it runs. Anyway you gotta take this into account when sizing relays.

One more thing capacitors when wired in series will have reduced capacitinace, 1/C +1/C but wired in parallel you just add them C+C. Probably doesn’t mean much to people but for electricians it’s useful if you don’t have the right size. Only connecting them in parallel is probably the only reason to do it practically.

    That’s too bad :(

    I love being trans! Best thing to ever happen to me. There’s parts that were hard and shitty and sucked for sure, I dont want to sugar coat it or pretend it isnt difficult. But for me its been about joy and euphoria for the last 6 years. Every day I get to wake up and be a woman, that shit rocks. Estrogen did so much for how I look and feel. I love having boobs, how my face looks. Im also very very open about being trans at work and in my personal life, and for me the anxiety about coming out or the anxiety of potential persecution (which is bad and I believe empirically is just as bad as actual persecution) was worse than the reality of actually being out. My coworkers got me a gift card and get well soon card for my upcoming bottom surgery, its very sweet (I work in healthcare). Ive commiserated so much with cis women about HRT, not having a uterus, the hegemonic feminine ideal, the patriarchy, dating men, all of that, we’re all in the same boat on so much.

    I do wonder what it is that made me euphoria first over dysphoria first in my own transition. Cause this has all been pretty great!

      I really like being trans too, it’s rough at times, though, not going to lie there. I’m lucky things in a big city in Australia are relatively chill compared to other parts of the world and that I have a healthcare job too where demand is so high, no one is going to actively discriminate against me. I like being open and talking to people about being trans. I’ve got lots of cis female friends and I’m great at deriving humour from my lived experiences.

      I’ve got a cis friend who went into premature menopause in her 20s and is basically on HRT just like me for her estrogen deficiency. I have another who has lost her hair from alopecia and struggles with the dysphoria that causes, as well feminine expectations and well meaning people going “oh but you can be a beautiful bald woman” and she’s like “fuck you I want my hair back”.

      I wish my issues were even close to cis women’s in this regard. We really are not in the same boat of problems, me and them.

      I’m glad you have that but nothing and no amount of euphoria will erase the absence of a real childhood and teens, as well as the torture of having dysphoria while having to watch my body go through male puberty…

      I could not wish that type of suffering upon my worst enemy. /gen

      E.g. being out and socially transitioning gives me panic attacks because it unlocks endless torrents of dysphoria since doing so highlights be never being AFAB…

      Also I’m more likely to rope before every getting that far, my brain is so aversed to any additional meaningless effort I seem to have to out in at least twice as much of just to get by, not even talking about fully transitioning (am only on HRT for now).
      I fucking despise and abhor all the deranged choices my brain has made for me and what I have to go through to make it not wanna kill itself

        I dont want to discount your pain.

        I dont really mourn my lack of girlhood and being an adolescent girl. I guess Im a little salty I missed out on being a hot bi college woman though lol. I watched my body go through male puberty too, I wasnt a fan either.

        Im not AFAB either obviously, but I actually quite like being transgender anyway which isnt somrthing I could get if Id been a cis woman. If I could redesign my life, Id still choose to be trans, I really do love it! I even socially transitioned before I did HRT, I did not pass even a little lol but I still did it and dont regret it.

        I get dysphoria too, it does hurt, I get misgendered - but less and less and less as time goes on.
