Phasors and impedance
Move from v(t) to the RMS phasor and summarize the element as Z = R + jX.
Key formulas
- Sinusoidal signal
The sinusoid v(t)=Vp cos(ωt+φ) is the projection of the rotating phasor.
- RMS value of a sinusoid
The RMS value Vp/√2 is the length of the RMS phasor.
- Impedance
Z=R+jX is the R and X legs of the impedance triangle.
- Phasor Ohm's law
Computes Phasor Ohm's law from the circuit model and the stated conditions.
