Understanding the Units
What is an Electronvolt?
An electronvolt equals approximately 1.602 × 10⁻¹⁹ joules — the kinetic energy gained by a single electron accelerated through a one-volt potential difference.
Common contexts: particle physics, atomic spectroscopy, semiconductor band gaps.
What is a Watt Hour?
A watt-hour equals exactly 3,600 joules.
Common contexts: phone batteries, small device energy.
