What is the energy acquired by an electron when it moves through a potential difference of 0.23 V?

[@RSA_Shock]

1.62x10-19 x 0.23 (eV=qV) Charge of one electron is 1.62x10-19 coulombs (q)

[@dstraight7084]

Thanks for this. For years, I have taken a passing interest in particle physics and saw this electron volt unit passed around, but I never understood what an electron volt actually is. Now I know. I also know that individual particles, even when accelerated to great speeds that can be achieved in particle accelerators, do not possess very much energy. Of course, the large number of particles in a beam generated in a particle accelerator will collectively have a lot of energy.

Bro I really thought this was an important constant, the energy of a photon or something

[@pianoslayer2516]

Hey, I'm trying to figure out a key detail. I know that when particle physicists measure the mass of a particle, they divide units of energy by velocity squared. For example: MeV/c^2. My question is: why do they use the speed of light? Why not another velocity?

[@buckyball2003]

I think that comes from the equation E=mc^2 rearranged to give m=E/c^2

[@binita4672]

@@buckyball2003 yes exactly. Also because speed of the light in vaccum is the highest of all.

[@tarunpal9622]

because this universe follows Einstein relatively phenomena and speed of light is taken as const because it doesn't depend on frame of reference

[@AryanSingh-yb2my]

Ik it has been 2 years since you asked this, but still C, which equals to 3*10^8, is not only the speed of light, but of all ElectroMagnetic waves, hence they use C

2:11 what is the distance between the two plates?

[@MrFrostyoo0]

I guess I am a bit late but anyways. It could be any distance, the only thing that matters is that the potential difference between the two plates must equal 1V. [At least that's what i got]

[@bananabird7584]

Hey, this video is really good, but I need someone to help me out. When converting joules to electron volts, why do we put the joules as a reciprocal?

[@sanjitraman]

If you agree with the fact that 1eV = 1.6x10^-19J, if we divide both sides of the equation by 1.6x10^-19J, the equation is: 1eV/(1.6x10^-19J) = 1, i.e 1eV *per* 1.6x10^-19J (and hence the reciprocal) Suppose you want to convert 5 Joules into electron Volts. So, if we multiply 5J by (1eV/(1.6x10^-19J)), we should still have the same value as we multiplied by one. The advantage of this is that now, 5J * (1eV/(1.6x10^-19J), the Joules cancel out, and we have an answer that is only in eV. The result is 5 / (1.6x10^-19) eV. = 3.125x10^19 eV Hope that helped :)

[@bananabird7584]

@@sanjitraman First off, thank you for your time to type that example. Secondly, from what you've given me, the reason why we have the reciprocal is because its easier to cancel out the joules and therefore end up with Electron volts, please correct me if I'm wrong. Also for your last answer, how come its 5 / 1.6x10^-19? Where did the 1 electron volt go?

[@alinashaikh5284]

Hello, the ans to ur question is that 1 eV is the work done by the electron and since we have established that W= qV we take 1eV=1.6x10^-19C x 1V(= 1J/C) Hence the C In the reciprocal. Hope this helps!

[@abhisrivastav7093]

Tooooo much love ,thank you ❤️❤️

[@AgentSuperSid]

Tnx for clearing my doubt

[@rassmi891]

Why isn't q taken as a negative value?

[@mikeynexus3433]

it is, but the velocity is also negative as field direction is defined by the force on a positive charge

[@AnkitaTiwari_no1]

Thank you so much sir🤩🙏🙏

[@AfridHassan12]

best video 2020

[@imitatioDei]

1.6 × 10 to negative 19 how do you solve that equation?

[@MaximumDorifto]

so you should have a data sheet with different physcial quantities on it like the charge on an electron, planck's constant, Hubble's constant, mass of an electron, proton or electron, the charge on an electron is a value you will not be expected to calculate as it should be on the sheet so you can just read it off (in physics atleast)

[@kartikeysiwach8471]

THAAAAANKYOU A LOT.

[@mohamedbabiker6653]

what is meant by mechanical energy, whats is the difference between mechanical and kinetic energy ?

[@michaelnevsky7622]

mechanical energy is the sum of kinetic energy and potential energy toghether.

I’m confused on your multiplication especially the 40(1.6*10 problem how did you end up with 3.2

[@ChickenPermissionOG]

why electrons mass and how far are the plates because 1v can not cross the air.

[@sefalibhakat143]

[@10_vittesse]

Just like u and the Mev

[@JjPoncho-ze6dx]

I’m confused how you got 4 ? When you multiply 250*1.6*10^-19

[@local_potato]

just put the values in calculator you will get 4*10^-17 Joules

[@kiva860]

How do you 250v =4

[@patrickparmer1648]

Divide 4 into 250 parts. Each part is equal to .016. So V=.016

[@michaelabbet8920]

I work in the electrical field for well over 40 years and I must say that this explanation is a joke. It does not clarify how the unit of one electron volt is derived. The video only spends about 30 seconds of the listed subject matter "Electron Volt Explained" and then diverts to other electrical topics. Sir! my advice to you that you need to clarify in your mind what you intend to argue before you open your mouth. It left me totally confused and I resorted to other videos for assistance.
