@derekowens I wish you can show us an example of that
People like you are the reason for many bright students! Thank you very much for all your efforts in producing these videos.
May i say I LOVE YOU
oops, i didnt watch the whole video
Since 1 coulomb is 1000 times larger than a millicoulomb, then would the equation 9×10^13(mc)(mc) over r^2 be ok? *I dont know the millicoulomb sign.
how cn u dislike dis itts great thnks
@x0xbethaNyyx0x that is the value of “k”
thank you Mr. Owens!
Thank you Mr. Owens.
brilliant!
wait a minute
capacitors have charge=> Q=V*F so if i have a cap bank of 40volt 3300uF then it means i have charge of 40*0.0033=0.132Q then this means that capbank’s possitive is +0.132Q and negative is -0.132Qand lets say there is 1 meter distance between them(to make it easier to count) so with the coulombs law this means that there is a force of 156,816,000 newton between negative and possitive wire impossible … static electricity is current electricity with very little amperes?
What software are you using for your videos (to write, etc.)?
@x0xbethaNyyx0x That’s the electrostatic constant. It’s one of the constants of nature. It simply shows up in Coulomb’s Law. The size of the number tells us something about the strength of the electrostatic force.
this may sound REALLY stupid, but at 1:04, where did you get the 9 from?
@derekowens sir can i use 1/4^eo rather than using k
Please continue your tutorials, they help alot.
@derekowens it is an SI unit so it cannot be reduced?
just one question:
whats is 1/[4(Pi)(epsilon)]
the epsilon is with a subscript 0
Lmao. I let my friend borrow my physics notes because her printer was broken. Then I reprinted my notes without any of my work. I was frozen because it’s a new subject for us and there’s a quiz tomorrow. Thanks to you, I am able to get this down even without my notes. Thank you. I will send this video to my friend now
Before i saw that video i was very baffled
Thanks
Did someone mention the word “simple”?
i wish you were my physics teacher…all my teacher does is print out someone else’s notes from the internet and gives them to us barely explaining whats going on. Thank God for people like you sir. Bless you
@derekowens Thank You for answering my question. I have to say that all of your videos are really helpful too.
