Question

$\mathbb{1 e V = ????}$​

Answer 1

Answer:

1.6 × 10^-19J

Explanation:

The actual value of 1eV is 1.6×10^-19J

As electron volt is the “unit of energy” also.

So, it is the amount of energy acquiref or lost by an electron as it traverses through a potential differnce of 1Volt.

Simply,

K.E=qV

K.E=(1.6×10^-19)×(1V)

So

K.E=1.6×10^-19J

This amount of energy is ONE Electron Volt.
