The Composition of E-Waste
Electronic waste, also known as e-waste, is made up of a wide variety of different materials. The category of waste can include everything from toys and consumer electronics to medical equipment to telecommunications equipment, all of which have differing amounts of nearly every type of common materials (plastics/polymers, glass, metals, ceramics, semiconductors, etc.). By weight, iron, plastics, aluminum, and copper make up the majority of many e-waste materials. Looking at value, though, precious and scarce metals make up most of the cost (such as gold, silver, and palladium, or selenium, tantalum, and germanium).
Beyond that, many forms of electronic waste contain toxic or hazardous chemical such as arsenic, lead, mercury, or chromium:
Batteries and cathode ray tubes often contain lead
Mercury can be found in thermostats and sensors, in gas discharge lamps and many printed circuit boards (PCBs)
Liquid crystal displays and printer inks and toners should be treated separately and chlorofluorocarbons, hydrochlorofluorocarbons, and hydrofluorocarbons can be found in electronics such as refrigerators with insulating foams
To give an example for all these facts, let's look at mobile/cell phones:
Phones are said to contain ~40 different elements
Of the most common materials by weight, phones are ~43% plastic, 7% iron, 3% aluminum, and 13% copper
Looking at precious metals, phones are ~3000ppm silver, 320ppm gold, and 120ppm palladium (approximated as over 90% of the value of the phone in terms of raw materials)
Rare earth metals can be found in many places in a phone, include the screen, circuitry, and speakers. Vibrating cell phones are usually thanks to neodymium, dysprosium, and/or praseodymium.
Phone batteries are typically lithium-ion but older phones especially can have nickel-metal-hydride or nickel-cadmium batteries
The plastic casing is typically polycarbonate and/or acrylonitrile butadiene styrene
Chargers are mostly copper and plastic, but can contain flame retardants that can include gold, cadmium, or bromine

When an iron rod is inserted between the coils the magnetic flux through coils increases. This happens because iron is a ferromagnetic substance and it lets more number of magnetic lines of force to pass through it.
1. Since, flux increases, the induced emf also increases, hence, the deflection of the galvanometer also increases.
2. Since flux increases, the inductance also increases which means that Inductive reactance of the inductor in an ac circuit will also increase. This will cause decrease in current through the circuit and hence brightness of bulb in series with inductor, will decrease.

The bros, during exams
Yudhishthira
Has prepared notes
disapproves cheating
sleep deprived as usual
is giving tuitions to others even at this point
Bhima
unaware of the syllabus till the last moment
tries to study, but fails
but hey, he has home science, so who is the real winner here
"hey guys, I was wondering about the taste of potassium nitrate, should I go taste some?-"
Arjun
can and will ace this test
leaves everything behind to study #chidiyakiaankh
but still sobs to Krishna about his troubles
says that he will fail ends up scoring 99%
Nakul
spends time in making chits instead of studying
has a whole book ready about methods of cheating
cheats and ends up scoring higher than the one from whom he cheated
"why should I study when I will become a celebrity?" *flips hair*
Sahadeva
wonders why he took PCB should have pursued astronomy instead
makes all sorts of coffees before exams
aces the practicals
dutifully organizes study sessions with Yudi

Sorry if you've already answered this but being a bit of a tech nerd I have to ask: how do the in-card-pacitators "scientifically" work?
okay, oh boy, my moment is here! /j
I'm sorry it took me so long to answer, I started working on a reply, saved it as a draft, and then it got buried 🥲 but I got a shovel and started digging, so here I am, several months later, with an answer!
It's long, so I put it under a read more ^^
Before I go into it, I am very much an electronics amateur and it's been a minute since I studied circuits in school, so a lot of the gaps in the "science" I filled with magic, so. Take it with a grain of salt.
The basic concepts behind the in-card-pacitators were inspired by two things: those pens that were really popular at one point that allowed you to "draw" circuits and PCBs on paper with electrically conducive ink; and static shock. I like the fan theory that ectoplasm conducts electricity really well, and since Danny has drawn sigils with ectoplasmic paint, I figured he could marry science and sigils again with the cards. If ectoplasm conducts electricity well, it seemed logical to conclude that ectoplasm is full of ions.
The show doesn't really go into how overshadowing "works", so I came up with my own explanation. When a ghost tries to overshadow someone, they have to extend their 'ectoplasmic field' and take over the electric synapses of the person's brain they're trying to control. Assuming ectoplasm operates on a different layer of reality, the electromagnetic field is an area of overlap between 'ghost stuff' and 'not ghost stuff'.
One more thing that has been touched on but not thoroughly explained in IYGABAB-verse is that: 1)ectoplasm is ectophilic; unbound ectoplasm is prone to sticking to larger sources (like: ghost cores, ectoplasm rifts, sigils, etc); and 2) ecto-ice is particularly attractive to ectoplasm; it has a "purifying" effect, but in practice this means it acts like an ecto-magnet. (important to note that although ice and ecto-ice share many qualities, like being cold and being less dense than the liquid state, ecto-ice is not actually ice, and therefore possesses qualities that ice does not have)
Okay. So all that is base level. Going back to the cards and how they work, the most important question is: how are they 'powered'? Where does the shock come from?
The idea here is inspired by static shock and what causes it. I know it's different from AC/DC electricity, so that's where ectoplasm does the heavy lifting. Because most humans don't have their own ecto-field, they wouldn't generate ecto-static (which in this case would be the transfer of ions from one ectoplasmic object to another when they rub against each other, like socks and carpet. But ghost!). Basically, the "capacitors" in the cards are made of ecto-ice, which collect these negatively charged ions, and when a ghost tries to exert their ecto-field on a person holding the card, the circuit connects and the ions jump to the ghost. Boom. They're shocked. Not unlike when you touch two charged capacitors together (to anyone reading this who doesn't know: don't do that. It's dangerous)
So that's basically how they work, and any gaps that make that not make sense scientifically....well no one really understands how magnets work, right? Blame the magnets.
