Question

Out of electron volt and kilowatt (units of power) which one is greater and by what value??

Answer 1

1 ev = 1.66 ×10^-19 J/s
1 KW = 1000 J/s

hence kilowatt is greater unit of power.
1 ev = 1.66 ×10^-16 KW

Answer 2

Kilowatt is greater unit of power than electron volt
We can compare them by converting both the given units into joules.

1 ev = 1.66* 10^ -19 J/s
1 KW = 1000 J/s

Now subtracting them.,
we get that kilowatt is 1.66*10^ -16 J/s greater than electron volt
