Description
AC Theory
1 electro-magnatism
1.1 lines of flux
1.1.1 lines of flux do not cross
1.1.2 lines of flux flow from north to south
1.1.3 flux can be the same but with different density
2 EMF
2.1 magnetic flux density = tesla(Wb/m(square))
2.2 magnetic flux= phi= (Wb)
3 AC sin wave
3.1 Frequency= f = Hz
3.1.1 Frequency= 1/time period
3.2 V avg=0.636*V peak
3.3 I avg= 0.636*V peak
3.4 V rms= 0.707*V peak
3.5 I rms= 0.707*V peak
3.6 V peak= 1.414* V peak
3.7 I peak= 1.414* I peak
4 Transformers
4.1 step up transformer
4.2 step down transformer
4.3 Delta/star
