Power Triangle
In AC circuits, current and voltage are normally out of phase and, as a result, not all the power produced

Resonance, Resonant Frequency, Series and Parallel Resonance
In the posts on inductance and capacitance, we have learned that both conditions are reactive and can provide opposition to
Impedance in RLC Circuits
Impedance in an R-C-L series circuit is equal to the phasor sum of resistance, inductive reactance, and capacitive reactance (Figure
Impedance in RC Circuits
In a capacitive circuit, as in an inductive circuit, impedance is the resultant of phasor addition of R and XC.
Impedance in RL Circuits
Impedance is the resultant of phasor addition of R and XL. The symbol for impedance is Z. Impedance is the
Impedance
Whenever inductive and capacitive components are used in an AC circuit, the calculation of their effects on the flow of
Capacitance and Capacitive Reactance
Capacitors The variation of an alternating voltage applied to a capacitor, the charge on the capacitor, and the current flowing
Voltage and Current Phase Relationships in an Inductive Circuit
As previously stated, any change in current in a coil (either a rise or a fall) causes a corresponding change
Inductance and Inductive Reactance
Inductance Any device relying on magnetism or magnetic fields to operate is a form of inductor. Motors, generators, transformers, and
