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.
