Radio and Electronics Formulae
- a quick reference for those radio and electronics formulae or
formulas for calculations that are so easily forgotten
There is a huge number of formulae, formulas or calculations
that appear in radio and electronics circuits and other areas of radio and
electronics. Everything from calculating the capacitors in series and parallel,
through the charge on capacitors, and flux in inductors through to calculations
about signals in feeders and the like. They are all important and often
difficult to remember. This section of Radio-Electronics.Com aims to provide a
quick and easy reference for them.
