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).
