No, this is not a stupid question at all! Converting volts to electron volts is a common conversion used in physics and can be a bit confusing at first. The key thing to remember is that volts (V) are a unit of electric potential or voltage, while electron volts (eV) are a unit of energy.
To convert from volts to electron volts, you need to use the equation:
1 eV = 1.60 x 10^-19 J
This means that 1 electron volt is equal to 1.60 x 10^-19 joules. So, to convert a potential difference measured in volts to electron volts, you need to multiply the value in volts by the conversion factor of 1.60 x 10^-19.
For example, if you have a potential difference of 10 volts, the conversion to electron volts would be:
10 V x 1.60 x 10^-19 J = 1.60 x 10^-18 eV
So, in short, to convert volts to electron volts, you need to use the conversion factor of 1.60 x 10^-19. I hope this helps clarify the process for you!
