 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 = 40*(10^-1)Joules = 4 Joules

 Rakesh said: (Sep 22, 2016) Please explain in detail. How can I solve?

 Vishalakshi said: (Nov 26, 2016) Your explanation is clear and correct @Saichaitanya.

 Anomi said: (Jul 26, 2018) 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.
