Electrical Engineering: Ch 6: Capacitors (1 of 26) Basics (What is a Capacitor?)

In this video I will explain the basics of capacitors, their equations with respect to charge, area and distance between the plates.

Next video in this series can be seen at:

I believe that some people have a gift to teach and you sir you are one of them

[tsegezabatsnafseged]

I would like to say, You are very legend, just you are absolutely amazing, and no word to express your contribution to this world. I wish some more people was like you in this world, and our world would be a nice place to live. God bless you and stay healthy and happy.

[ramkumarreddy]

sir you are genius, you are the best teacher i have come across

[anshulkumar-dysj]

Cool man. Loved the simplicity. Make more videos.

[jimihendrixx]

Great teaching. Got it right away. Thanks!

Capacitor is the most interesting component of an electric circuit. While no charges flow b/w its plates, it induces magnetic field around plates during charging & discharging, proving it is not motion of charges but motion of electric flux which induces magnetic field & vice versa. It is not clear what happens in the space b/w the plates during charging & discharging of capacitor. But, since cirulating M-field of opposite direction appears momentarily during charging & discharging electric flux must also be moving in opposite direction. Since motion of flux produces measurable magnatic effects it can't be something imaginary but physical & tangible. My guess is, due to destructive interference electric flux relocates, reducing flux density b/w plates. This creates a kind of 'space vacuum' b/w plates producing attractive force. During discharging reverse process happens & flux returns back. Opposite motion of electric flux induces magnetic flux of opposite direction. If we replace current with electric flux in Maxwell's 4th equation it would make 3rd & 4th equation reciprocal i. e. moving magnetic flux induces electric flux & electric flux induces magnetic flux. During charging & discharging, capacitor could be breathing electric flux and exchanging energy with space.

Hi Prof. Biezen,

I looked at your Electrical Engineering lecture series and found that you didn't include videos 15-20. Were those videos skipped intentionally?

[xXxserenityxXx]

Add that the constant is based on materials used for the plates

[d_naijaentertainment]

me watching in 2024 and you are doing the most. Thanks to you I understand.

How do you calculate capacitance if area's of plates of capacitor are unequal?

[RiaziMohandesi]

Dear Professor, what is the difference between this chapter and the previous, both are about capacitors but this one includes electerical engineering?

[rubahasan]

what is the name of the book that you use it in your videos?

[mrjknnl]

Thank you teacher
The explanation is very nice

[vijayasimhareddy]

How current flows through dielectric material sir

[akechwolmayom]

Hey professor Michael thanks you, I really wanna to reach you please, because I got a lot problems in electrical engineering course, I been using your videos of all course of electrical engineering .please can I hit you my email for more details and ask some questions .
