Intrinsic Impedance of a Medium or Wave impedance.
Intrinsic Standoff Ratio in UJT (Unijunction Transistors).
Zeta potential, also known as “electro-kinetic potential”.
Damping ratio of an oscillating system or Damping Factor “ζ (zeta)”.
Emissivity (It is a measure of an object’s ability to emit infrared energy).

It is easy to memorize (& remember) the value of different quantities and constant values by using Greek alphabets instead of using their name.
and X,Y,Z as variables, So we can’t use the same alphabets and letters for too many different terms in scientific & engineering fields to avoid making confusion.
Latin & English alphabets are widely used like A = Current in ampere, V = Voltage in Volts, P = Power in Watts, R = resistance in Ohms etc.
Now, we follow the same and use Greek symbols in most engineering and scientific contents and technical papers.
The main reason to use Greek characters and symbols is the continuity from the ancient Phoenicians to Greek adoption and used by philosophers ( from BC 750+).
The Greek letters as special characters and symbols are used due to the following reasons. Why are Greek Alphabets Used in Scientific, Mathematical and Engineering Disciplines?

In this post, we will show the uses of 24 Greek alphabets especially in electrical and electronic engineering. Keep in mind that the lowercase and uppercase (small & capital) letters are used to denote different values in different science and engineering disciplines. There are a total 24 Greek letters which are widely used in engineering, science and mathematics applications which indicates different characteristics and measurement of specific quantities.
