This video introduces and explains the Electronvolt for A Level Physics.
In everyday life we use the joule to measure energy. When we consider the energy of individual particles or photons, it is often more convenient to use a smaller unit: the electronvolt, eV.
ELECTRONVOLT DEFINITION: THE ENERGY GAINED BY AN ELECTRON ACCELERATING THROUGH A P.D. OF 1 VOLT
Thanks for watching,

so does that mean that an electronvolt is the same as the potential difference?
OMG, I didn't know like how the electronvolt is the electronvolt, like how you work out the value, in other words proving it which makes it easier to understand. I love your videos sir, the way you explain it in detail makes everything seem clearer.
Did you know your videos are used to teach physics on Up Learn? It's a paid subscription and when I did the free trial realised its your videos which we can get for free on yt
but i thought the charge of an electron is -1.6 x10 to the -19, so shouldn't an electron volt be negative?
Alright cool, good to know. But what does Pd stand for?
Who’s bingeing these videos right before their exams
thank u that was helpful
Hey man, after watching a few of your videos including young’s double slit, I must say you really made me understand physics better as you sound confident in your answers as well. So I just want to say thank you and have a great day, sir!
Your English is too fast I don't understand your topic
Very clearly explained
.23 ELECTRON VOLTS
isnt that a LEGO block?
The teaching part went a bit too fast I kept on pausing. But I still understood some parts.
this helped me solve a lot of confusion, thanks fr the vid.
thanks i was lost in this one
SLOW DOWN!!!!!!
Since electron is gaining kinetic energy of 1eV won't it be losing equivalent amount of potential energy since Potential energy change would be equal to -1.6*10^-19 J so mechanical energy remains conserved
When can you use KE=eV and when can you use KE=1/2mv^2?
this is kinda a random question but do you have a video on how to reduce uncertainty in any experiment. I have a feeling for the new specification they are going to put heavy emphasis on uncertainty in section c
I trust a guy with an accent teaching physics.
It would have been better if you had included all the units in the intermediary step starting at 1:40.
Have you done/ or know of videos which help with converting from kg
–> neVc^2 and vice versa? Where n can be M, G or T.
