ETA313-02: Theory lesson 1: Electric components
Recommended reading: KonCEPT page 5-83 (chapter 1&2)
In this course sqrt(-1) is banned! We do not know how to derivate/integrate… and so on.
This first lesson covers all components except the most difficult one, the transmission line. It is covered in the antenna lesson.
- Ohms Law. U = RI, P=UI, thermal efficiency (mu).
- Decibel: x dB = 10 log (power level / reference power level) = 10 log ( [voltage^2/R]/[ref voltage^2/R] ) = 20 log (voltage/ref voltage)
