Electrical and physical constants

- table or chart of the electrical and physical constants used in a variety of ways including in electronics design.

There is a large number of physical constants that are used in physics and electronics engineering. These constants can be used in a variety of electronics calculations and may be very useful on occasions. Although not widely used in electronics design, they may nevertheless be used on occasions.
