Electric Potential Difference (Voltage)

[@el_witcher]

I finally understood Electric Potential. Thank you very much, Sir. Greetings from Germany!

great lecture sir, my all concept gets cleared.

Great sir 👌😊

Thanku so much

As you said in the last lecture that battery with the positive terminal attracts the electrons present in the copper wire . In this video you had taken conducting plate which is equivalent to the positive terminal of battery and in this example you had indicated the electric field but here there is no copper wire then from where electron is coming and attracting toward conducting plate . then how can we say electric field is existing.. I want to know from where exactly electrons are coming and attracting toward the conducting plate

[@nahuel3256]

the electrons come from God

Electric field creating by source charge... That source charge meant net charge particle( atoms have both electrons and protons present in the Neucleous, charge particles charged by losing and gaining electrons, so net charge means q=np+ne( no of protons adding no of electrons) it means that particle having more number of electrons it is negatively charged particle, larger number of protons means positively charged particle. In that case this plate is positively charged particle so it repulse the test charge it also a positive charge. Like charge repels unlike charges attract. And you said electrons coming from copper wire... It's wrong electrons are from atoms present in the copper wire. Copper wire is metal it has more number of electrons in their atoms.. Electric field is determines how force of attraction and replulsion takes place between two charged bodies...

Great

sir isn't current a tensor quantity?

[@minimalmood2469]

Yes. But we can say current as scalar since scalar is a tensor quantity with it's rank is equal to zero

[@starkendeavours7072]

@@minimalmood2469 How tensor is a scalar quantity? and how rank is coming into picture ?

[@saurabhmaurya4020]

It's a pseudo vector quantity

you said that Voltage is scalar quantity and voltage is nothing but electromotive force but force is vector quantity then how voltage is scalar???

[@kadhasollaporom4221]

Bro a vector quantity has magnitude and it's own direction but voltage has magnitude and directions too but we can't assure that it will go in same direction it can change its direction whenever the field gets changed so we can't give voltage a direction so it is a scalar quantity

[@nahuel3256]

the dot product of two vectors is a scalar
