Thoughts On Vaping After One Month Of Being A #ChristianDadWhoVapes

-Vaping is hilariously uncool looking yet most people who do it seem completely oblivious to this fact.

-There are thousands and thousands of flavors to choose from. Three of them are good.

-“Vape Culture” is gendered in a way not unlike gaming culture and it’s gross and bad.

-Some of these devices can be dangerous given the fact that you’re powering low ohm resistors with high-drain batteries with a 35 amp limit. Get ready to have a guy with a storm trooper neck tattoo explain Ohm’s Law to you in a 32 minute YouTube video.

-All Vape videos are no shorter that 12 agonizing minutes. (See above).

-Vape branding is a confusing tug of war between mid-2000s mixology aesthetic and a UFC t-shirt and no one seems to notice or care.

-Vaping is essentially swapping one vice for a substantially-healthier-but-still-probably-not-good-for-you one but having your tastebuds and lung capacity back is nice.

-Nothing is more embarrassing than waking up and thinking to yourself “Guess I have to go to the vape store to get more flavored nicotine juice.” Nothing.

More Than You Ever Wanted to Know About Electrical Engineering, Part 23: Working With Impedances

If you’re dealing with a complex network, you can combine impedances in series and parallel just as you can with resistance, capacitance and inductance. Impedances combine like resistances: for series combinations, they add, and for parallel combinations, the inverse of the total impedance is the sum of the inverses of the component impedances.

You can also use a more general version of Ohm’s Law to deal with impedances. Instead of just resistance, we can now relate voltage, current, and impedance.

If Ohm’s Law holds true, that means that KVL and KCL also hold true. With an understanding of impedance, we can essentially treat complex circuits involving capacitance, inductance, and time-varying sources as if they were simple DC circuits containing only resistances. This will make our lives a thousand times easier. The only tricky part is translating the voltage, current, and impedances you’re given into a form that will let you manipulate them easily.
