There's thousands of comments alike, but even still, I owe a significant part of my degree to this man. Thank you!

[@southpoleelvs]

This is so funny that what took my physics professor with a doctorate in physics three hours to teach took you 17 minutes. Keep it up!

[@raj-cr4nl]

And for freaking FREE.

[@TiberiusStorm]

Some people love to complicate things. Especially Physics professors!

[@alexv5581]

Your comment is so funny that your professor that has a doctorate is a scientist, not a teacher. The university hired him to do research, and if he is a good teacher than that's just a bonus. Students don't seem to know this. People just look to blame other people or circumstances for there failures. Suck it up and do something different to learn the material. Its annoying hearing all the excuses my classmates come up with.

[@alexv5581]

@@TiberiusStorm Do you know why? Because physics professors are physicists. They assume you want to be a scientist or engineer. So some feel the responsibility to be gatekeepers. They will see if you really have the work ethic to make it. This is especially tough for students who skipped physics in high school. Long story short, I did skip physics in high school for personal reasons but I am now a physics major in my junior year. You want something bad enough you go get it. It is your priority above anything else; sex, video games, and etc. Sometimes you need to sacrifice time with your family.

[@TiberiusStorm]

True enough! I'm sacrificing a lot to be in college but sometimes the concepts and/or calculations just elude me and I get discouraged. I also missed Physics in high school so I'm doing double duty trying to understand and learn the basics.

[@peral7645]

literally was in my physicis tutor lab for 2 hours and you explained it all in 17 minutes....

[@SuperStarEevee]

thank you! i could not for the life of me understand a word my professor was saying this year, which became a problem when he actually taught us something I didn't know yet, so it's nice to have videos like these!

[@joshgiesbrecht]

I'm taking a $150.00 Udemy course, and the teacher just blazed through this, gave a single example, but explained it horribly and just moved on. I still had no idea how to actually use the formula or exactly what we were solving. I spent the last 45 minutes trying to use what he taught me to no avail. After just 6 minutes of watching your video, I understand it completely. You have earned a sub and I will be coming here to supplement the Udemy course. THANK YOU!!!!! You're a very good, straight forward teacher. Edit: Oh, wow. You went above and beyond. He didn't even attempt to teach us all of the other stuff, like finding the number of time constants to get to a certain percentage.. I'm not a math guy, so you really have saved me here. Thank you 🙏

[@SS-pn7ss]

You explained this so perfectly, you make me more passionate about the subjects you teach. Thank you so much for all these magnificent tutorials, wouldn't pass my semester without them!

[@ColdHawk]

I wish this had been around back in the day when I was in school… and I do mean BACK in the day. Way back when the internet was shared only between research organizations and government agencies, and before the first website went live, I conned my way through the stand-in-line-to-get-a-stamp-on-your-sheet college registration process to get into a couple of courses without having the prerequisites (which I probably could not have done quite so easily in the time of modern electronic records) and had to work hard to keep up, using old textbooks to cover gaps in knowledge. Turns out that is pretty hard to do! As it is, in my fifties, still stubborn, and still taking on new challenges, I am truly humbled and grateful that someone would go to the effort to share their gift for teaching and put out content like this.

[@Natalita274]

4:00 "let's talk about the time constant" (never explains what the time constant is) I finally get it I think but personally I would have appreciated a bit more explanation, especially on the difference between t and Tau. You switched to using t to represent it and i got so confused and stressed wondering if seconds and RC were the same thing, then later on you convert them... Also more explanation about the 1-e etc equation at around 4:45? physics isn't my strong suit lol

[@Exoudar]

As always, very informative!

[@BelaCurcio]

Another method for "How much time does it take for the capacitor to reach 90% charge?" Just keep plugging in "e to the power of x" into your calculator (or just the google search bar) with reasonable guesses for the power. You want the result to be 0.1, which is 10% left, because you know that e to the power of (-t/tau) is equal to the percentage you will have LEFT TO GO at any given point. After very minimal trial and error, you get approximately 0.1 for the answer when you plug in "e to the power of -2.3". Now that you have the correct power, you know 2.3 = t/0.5. And thus t=1.15 seconds.
