Confusion between Volt and ElectronvoltWatch
and of the electronvolt - energy gained by an electron as it is accelerated through 1p.d
In calculations I've always used the same value for eV and V so 1ev = 1V and 444ev = 444V and my classmates agree you can do this plus I come out with the right answer.
But come to think about it how can 1V = 1eV.................
because eV = elementary charge * voltage
so then 1V would surely be:= (1.6*10^-19) * 1
also the specification says eV = 1/2mv^2 as an energy transfer equation but surely the KE part would be in joules...... yet here it equals to electron-volts. I understand that the electronvolt is also a unit of energy but it needs to be converted from joules first surely.
So shouldn't it be eV = KE(in joules) / elementary charge.
This probably all seems really confusing because tbf I really have no idea what I am on about but I'm so confused so if you are an expert in the field please do help Thankyou!!!!
I do OCR A and have my unit 2 exam in a week so its kinda help for that!!
