Electric Field (2 of 3) Calculating the Magnitude and Direction of the Electric Field

An electric field is an area that surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them. Electric field is abbreviated as E-field. Electric fields are created by electric charges. The electric field strength is defined as the number of newtons of force per coulomb of charge.

The SI unit for electric field strength is volt per meter (V/m) or Newtons per coulomb (N/C) is also used as a unit of electric field strength. On an atomic scale, the electric field is responsible for the attractive force between the atomic nucleus and electrons that holds atoms together, and the forces between atoms that cause chemical bonding. Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces of nature.

After an hour of searching, this video has saved me. Did not think F=ma would show up with electric fields and would never have thought of it.

@Merna Chaldo, Just wondering....Where is your university?  Thank you for the very nice comment, I could use a few blessings.

[lopezmarlen]

Why can't physics professors be like you? You're so clear and understanding, I'd give anything to be taught under you rather than my super-confusing prof :/

[ElizabethRodriguez-lkuw]

Your videos are so helpful and very clear. I've been having trouble understanding my professor and you did very well explaining. You didn't skip any steps, which is what a lot of professors do. Thank you and God Bless!

The best I can get before standing in front of my class tomorrow explaining Electric Charge and Electric Field. Appreciate you. You deserve my subscription. many Thanks and hope to watch more of your videos...

[merna]

May you please start teaching at my university ? 
May God bless you with every kind of a blessing

These videos are fantastic! I love the graphics, you speak very clearly, I'm really getting something out of these videos, thanks for your time and effort!

[michaelgich]

this video helped me more than an hour of study thanks a million

[palmapanfu]

You sound like the guy from KhanAcademy! Great video, really helpful for revision for my final.

Actually after reading and trying to understand Lecturer's note power points are hard to understand, but in this video you show more clear and better understanding
thanks for video lesson, i understood more better than reading lecturer's power point notes. really fast and clear understanding  got with this video, i hope your videos will improve my physics understanding more better.

[drmazanie]

for a beginner in physics I found this so helpful in understanding the concept. thank you

[cooljussel]

Ty, it was a clear explaination in contrast to my teacher who makes it confusing as hell. Keep it up!

[UndertakenProduction]

Thank you very much for your videos. Without them I would not do well in class.

[MrAlbashiri]

Nobody explained it as simple as you did. you there the best.

[blake]

These are really helpful. I have a physics final coming up on monday. Thank you!

[MJ-tnqp]

Really helpful, you nailed the difference between electric field and electric force for me. Thank you 🙏

[elchopoinsurance]

I appreciated this video. I was able to understand the Electric field concept. It was causing me a nightmare because I was unable to distinguish the Fe and Ef concepts. Thank you so much, you are a physics saint and life saver. Please continue posting more videos.

[rickyortiz]

I really appreciate you using the units as much as you do. It is really helping me!

[Noor-sqtm]

hey I am watching your video in 2019 and you had uploaded it in 2014....wowwww

[renzosilva]

wonderfully explained, sir! thank you very much
