**What a volt (V) means?**

Volt is the SI unit for voltage, which is the difference in potential or electromotive force. One volt is equal to one joule per coulomb.

**What does elementary charge (e) mean?**

The smallest unit of electricity is called an elementary charge. It is a constant that is always positive and equals 1.602176634 10-19 coulombs. We use the letter “e” to stand for the elementary charge.

**What a electron volt (eV) means?**

An electron volt, also called an electron-volt, is the amount of kinetic energy that an electron gains or loses when it moves from rest through a 1 volt potential. A unit of energy is an electron volt. One electron volt is equal to 1.602176634 x 10-19 J.

**What a Coulombs (C) means?**

In the SI system, the unit for electric charge is called a “coulomb.” It is the amount of electricity that one ampere can move in one second.
