|I want energy equation.|
|Saichaitanya said: (Apr 7, 2011)|
|STANDARD VALUE of 1 eV = 1.6021 x 10^-19 Joule
In the Question
4 eV = 4*(1.6021 x 10^-19)*(6.24 x 10^18) Joules
= 4 Joules

|Q = NE
Energy Q equal to NE, whre N no of electron and E voltage.

|V = Joules/Coulomb.
thus, Joules = Volts * Coulomb.
Convert 6.24x10^18 electrons to coulomb.
1 electron = 1.60x10^-19 coulomb.
1 coulomb = 6.24x10^18 electrons.
Joules = 4(1) = 4J.
