AC CIRCUITS
|
1 Instantaneous Voltage of a Sine Wave:
V =Vmaxsin2pft
V = voltage [V]
f = frequency [Hz]
t = time [s]
2 Maximum and rms Values:
I=Im /Ö2
V=Vm /Ö2
I = current [A]
V = voltage [V]
3 RLC Circuits:
P avg = IV cos Æ
PF= cos Æ
4 Conductance (G):
The reciprocal of resistance in siemens (S).
5 Susceptance (B, BL, BC):
The reciprocal of reactance in siemens (S).
6 Admittance (Y):
The reciprocal of impedance in siemens (S).
