Electric Fields: Crash Course Physics #26

As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors, conductors, electric field lines, and how objects with net charge generate electric fields.

These videos are very well produced in general and Shini is a fantastic presenter. However I have a critique... and this is something that appears in a lot of the CrashCourse videos... After each sentence is spoken, there is always a very fast cut into the next sentence. The duration of the audio pause during the cut is similar to that of the space between words being spoken. So although it's a new sentence, it's jarring because linguistically it does not sound like a new sentence. And this continues constantly throughout the video. I know that the idea is to keep things fast and exciting, and this technique works great for entertainment Vlogs, but it doesn't work so well in teaching physics. The net effect after a few minutes of the fast cuts is viewer exhaustion. It's like a never ending sentence that is being spoken. I'd recommend changing the editing technique. Literally just 0.2s-0.5s of additional silence at the end of each large sentence will make a massive difference in the overall presentation. Plus you'll get more viewing time in your Youtube stats!

this 10 minutes summary of electric field will surely bring tears of happiness to faraday

I'm doing a PhD in electrical engineering (if that matters)... and I still believe the pace of the video is way too fast (or I'm just stupid).. also.. giving some examples to the concepts would ease comprehension greatly.. it's tough finding good examples for electrical stuff but still extremely important since it's impossible to visualize electrical concepts as easily as mechanical ones.

For everyone saying it's too fast, you can slow the video, like to .75, she sounds a little funny at first lol but I have found it helpful especially with captions. Just a suggestion might not work for everyone.

Listen in 2x for 40 sec then bring it back to normal.this way she seems slower.and all the best for you exam in less than 11 hours

These vids are great, but very reminiscent of when I used to goto Uni, be listening to a lecture- it starts off easy 'ah yeah I know this stuff', so I look away for a few seconds, look back at the lecturer has filled the board with complex maths. I need a coffee >_>

As someone who is studying Electrical Engineering, this is pretty had to keep up with. As I'm about to understand what she is talking about, she has already moved on to the next topic. It was a never-ending game of catch up.

I think one of the main problems with this video is that it's just throwing information at you and expecting it to stick. A great way to improve these videos is to add a worksheet linked in the description that has some corresponding questions, and then adding some pauses in the video that will request the user to try a specific problem while they pause their video. A second worksheet can be added with the solution to the questions. Active learning is the key to really understanding, not simply watching.

Tip for everyone that thinks the video's too fast:
1) Open inspector window (In Mac you can do it through command+option+i)
2) Type into the console: [insert speed here]"


You can now adjust the speed more accurately than options youtube gives you. Personally I find 0.95 the best.

[MrThepatrickshow]

The rapid pace, and jump cut editing of this video makes it nearly impossible to follow unless you already know everything ... and even then... it's hard to keep up.

[andrea-colw]

i just end up zoning out while watching because she talks so fast lmao

Thank you so much! I love all STEM CC and so far this is my favorite. I am so thankful this exists, and also for the great teacher.

[aurongreenland]

Being a electrical technician, this is pretty well done.

[arjenbij]

Crash Course music theory, please Hank!

[CHAS]

Great public service. Great refresher course. The material and presenter are spot on. This is a win for PBS.

[petroplindiesler]

The editing style is perfect

Don't change anything please

[darikraft]

Love these videos so much!! They're a huge help for when I don't quite understand a concept from my physics lectures. You guys should make one on center of mass and conservation of momentum! But really, any physics video you create is fantastic! easy to follow, engaging, and educational--it's perfect! Keep it up :)

Crash course algebra and calculus!! +CrashCourse
