Electron Constants

- table or chart of electron constants including symbol, value and units for values such as electron specific charge, electron molar mass, electron specific charge, etc.

Electron constants are used in many areas of science and electronics for a variety of calculations.

The electron constants that come under the universal constants heading include items such as the electron specific charge, electron molar mass, electron specific charge, etc.

Details for these electron constants and more are given below. The constant name, symbol, value, units and the relative uncertainty are provided.

GaN’s Ground-Floor Opportunity
The electronics industry has a major role to play in helping to save energy, by enabling better equipment and new ways of working and living that that are more efficient and environmentally friendly. Maintaining the pace of technological progress is key, but improvements become both smaller and harder to achieve as each technology matures. We can see this trend in the development of power semiconductors, as device designers seek more complex and expensive ways to reduce switching energy and RDS(ON) against silicon’s natural limitations.
