So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay, buckle up, everyone! Today, Shini has the task of breaking down electrical potential energy, electric potential, voltage, capacitors, energy storage, and potential energy... it's a lot!

Forget defibrillators, the 0.75 playback speed setting is the real lifesaver here.

come on, it's ok if your video exceeds 10 minutes, we'll still watch it!

Just a shout-out to anyone confused by this episode -- I am an electronic engineer by trade, and watching this video even I was bouncing between "that's technically true but so far removed from my day-to-day" to "wtf?". So if you found this confusing, do not be discouraged -- there are a wide variety of ways of teaching and understanding electronics, some of which may be more suited to your way of thinking. Do not give up!

I normally love Crash Course videos, but this one went completely over my head. Shini was waaaay too fast

@Ventura60kts 9 years ago

how about slowing down and taking a breath this video is an assault on the senses I've still no idea what a capacitor is

@naota3k 9 years ago

I swear. Capacitors get me every time. I've seen 26 episodes of this with no issues. As soon as the episode I want comes along, I just become lost in the matrix. Capacitors just absolutely destroy my brain for some reason.

Ok... so I am a senior computer engineering student who watches this series to refresh myself on the basics and I got lost at around 3 minutes. I know the material, but following this video actually started to confuse me. I am not 100% what the solution may be, but a slower more verbose explanation maybe helpful.

"Today we learned ... a lot."

Yes, yes we did.

Who here is during Covid-19 learning stuff.

This is A LOT to take in for a 10 minutes video .... This chapter was covered in 3 weeks at my college

@arthurabraham3271 9 years ago

I really hope CC Physics gets to 50+ episodes, it really is a massive subject and covering all aspects of physics properly will take more vids in this playlist than I think any other subject would.

@ArchiduquesaMA 8 years ago

this is really helpful for someone that has studied this subject from a book before, like it shows the examples very clear. I dont recommend learning directly from this video, you have to have a previous knowledge

@eemviews 9 years ago

Just for the record I would LOVEEE some math crash course. Either stats or calculus would be soo helpful!!

@mechailreydon3784 7 years ago

I was kind of lost during this video so I was very relieved when i saw many other people in the comment section felt the same.

@SheikhEddy 9 years ago

This is the first episode where I didn't understand much

@TacTwo 9 years ago

This is definitely the most difficult Crash Course to follow so far - my "CCPhysics" notebook is practically unintelligible - but that just means I need to focus more... and maybe purchase "Physics for Dummies" as a supplementary learning tool like I did with the Anatomy & Physiology course.

@jackdaniels4975 9 years ago

When you're going along with the video but then you get too many equations and you ask yourself "What am I watching again? sounds like noise at this point"

10/10 too complicated for me.

@pco246 9 years ago

I love this channel so much. It's more like crush course

@jtlackner 9 years ago

I may be a bit slow but I always seem to get lost with her explanations, while following along with just fine with other people they use to explain things I know nothing about... It's like I've been enrolled into a 201 class without taking the intro 101 class :(
