Wow ! This video explains it all with beautiful simulation. It explains when woyld electrons change direction, why current would be zero etc. Appreciate your effort to help students.
I may have said thank you for this video before, but my exam is in a week's time and I needed to see it again. I understand better the second time around than I did initially. Thank you so much for the great explanation.
i was so confused about this stopping potential...saw and read it in like a hundred other places but its here when i got THE BEST EXPLAINATION of my doubts about actual definition and use of stopping potential and that beautiful stimulation just explained everyyyyy thing i was confused about.....THANKS A LOT 🤗 so i subscribed!!
A bit confused, you said that the anode is the collecting plate however in your diagram it is negatively charged? From my limited chemistry, an anode has to be positive I thought?
Thanks a lot for explaining in such an intuitive way, and the simulation made it much much easier and interesting. And why does the current read 0 at the stopping potential?
nice video...only one i was able to understand properly -when electron moves to the negative plate why does KE be converted to potential energy(I didn't understand what u meant by potential energy) -what is the difference between photo electric effect and the photoconductive effect(the band theory one)...can photo electric effect be explained using band theory? p.s- i'm dumb and i'm sorry if this was obvious
Q. when electron moves to the negative plate why does KE be converted to potential energy(I didn't understand what u meant by potential energy9 A. The negatively charged electron is moving towards the negatively charged plate, since they have the same charge they repel each other. So the closer the electron get to the negative plate the more repulsion there is, it slows down and the more PE it gets. It does not want to be the negative plate. It is kind of like when you throw a ball up into the air, the higher it gets, the closer it gets to where it does not want to be and it slows down. When it it at its highest point it stop, all of its initial KE has been converted to PE it has the most PE and no KE. Does that help? Q. what is the difference between photo electric effect and the photoconductive effect(the band theory one)...can photo electric effect be explained using band theory? A. Sorry I have not idea.
hi, nice video!! but i have a question, why is that when we change the potential to negative (but not reaching -3.60V yet) the electrons are still able to pass thru the collecting plate and still produce electricity? the collecting plate is supposedly connected to the negative charge of the battery, and don't electrons move towards positive charge of the battery? it's been troubling me, and sorry for my english, im not a native english speaker. thanks!!

Glad to be helpful. Thanks for watching and subscribing! Best wishes.
Could not have asked for a better video, it is clear and well articulated with all the required information.
Thanks so much, very glad to hear that.
Really well explained. Appreciate the effort to make this so understandable.
Glad it was helpful!
You did a great job and the simulation made it very clear to understand the whole concept. Thank you.
Thanks for the comment and thanks for mentioning the simulation. I often wonder if people find them helpful.
@@stepbystepscience Yeah I found the simulation very helpful.
Thanks for the explanation, it was extremely helpful
Glad it was helpful! Thanks for watching!
great clear explanation..thanks!!!
You are welcome!
Using the PHET simulation and related calculations for my lab! Lucky! Great explanation.

the anode is negatively charged
Thank you! Super helpful video!
You're welcome! Glad it was helpful.
Brilliant explanation like always...
Thanks again!
amazing ty sir
Most welcome
Hey man..!! I'm from India..!! Your work is pretty good..! Keep rocking
Thanks, will do and greetings from Germany!
Thank uuuuu so much 💖
You're welcome!
thank you sir :)
Most welcome!
Thanks for ur explanation❤❤
You are very welcome.
Very nice sir,really like the study slides❤️
Glad to hear that. Thanks very much.
Thanks a lot for explaining in such an intuitive way, and the simulation made it much much easier and interesting. And why does the current read 0 at the stopping potential?
Because the "potential difference" between the two plates has "stopped" the electrons from reaching the positively charged plate.
@@stepbystepscience thanks a lot
Thank you so much 😊😊😇😇
Most welcome 😊
Hell yeah! Great presentation, many thanks!
Glad you enjoyed it!

A. Sorry I have not idea.
@@stepbystepscience Thanks a lot for your quick reply that analogy helped a lot :)
Thank u so much 😊
No problem 😊
What if Ek = 5.95eV ? Wo= 0 eV
What does that mean in terms of force produced
Thank you so much! You've helped a lot.
You're welcome. Glad to hear that!
Very well explained👏👏..Thanks a lot!!
So nice of you to say so, thanks!
helped me a lot. Thank you
Glad to hear that and thanks for the comment.
hi, nice video!! but i have a question, why is that when we change the potential to negative (but not reaching -3.60V yet) the electrons are still able to pass thru the collecting plate and still produce electricity? the collecting plate is supposedly connected to the negative charge of the battery, and don't electrons move towards positive charge of the battery? it's been troubling me, and sorry for my english, im not a native english speaker. thanks!!
Is cut off voltage and stopping potential same or different?
But wouldn't this deceleration result in the emission of EM radiation from the electrons?
Yes, moving charges emit electromagnetic radiation
I am confused. Why is the battery giving us a negative number that we then use as a positive in our equation?
you use the absolute value of the battery voltage for the stopping potential
@@stepbystepscience Thank you very much for clearing that up.
