Chapter 1 - The Fundamentals

The fundamental unit of electrical charge is the coulomb (C) defined below in units of elementary charge ^{1 1}elementary charge is defined as the electrical charge carried by a single proton

\[1\ C = \frac{1}{1.602176634 \times 10^{-19} } \ e\]

The measure of coulombs that cross a infinitely thin cross section of area in a second form the definition of current: the ampere (A)

\[1 \ A = 1 \ C/s\]
