AC circuits, alternating current electricity
Alternating current (AC) circuits explained using time and phasor animations. Impedance, phase relations, resonance and RMS quantities. A resource page from Physclips: a multi level, multimedia introduction to physics (download the animations on this page).. AC electricity is ubiquitous not only in the supply of power, but in electronics and signal processing.
Phasor
In physics and engineering, a phasor (a portmanteau of phase vector), is a complex number representing a sinusoidal function whose amplitude (A), angular frequency (ω), and initial phase (θ) are time invariant.It is related to a more general concept called analytic representation, which decomposes a sinusoid into the product of a complex constant and a factor that encapsulates the frequency ...

Phasor Diagrams It is sometimes helpful to treat the phase as if it defined a vector in a plane. The usual reference for zero phase is taken to be the positive x axis and is
AC Capacitance and Capacitive Reactance in AC Circuit
AC Capacitance and Capacitive Reactance. The opposition to current flow through an AC Capacitor is called Capacitive Reactance and which itself is inversely proportional to the supply frequency
AC Resistance and Impedance in an AC Circuit
AC Resistance and Impedance. Impedance, measured in Ohms, is the effective resistance to current flow around an AC circuit containing resistances and reactances
AC power
Power in an electric circuit is the rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow.. The portion of power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as ...
Series RLC Circuit — Collection of Solved Problems
The current is of the same size on all the components, the phasor of current I m is therefore the same for all the components and is usually drawn in the positive direction of the x axis.; The phasor of voltage is on the resistor U R parallel to the current phasor, because the phase difference between the voltage and current is zero – in this case voltage and current are in phase.
Electric Power Single and Three Phase Power Active ...
This energy is stored in form of static electric field. The power associated with a capacitor is also reactive power.. Active Power and Reactive Power. Let us consider a single phase power circuit in which current lags behind the voltage by an angle φ. Let the instantaneous electric potential difference v = V m.sinωt Then the instantaneous current can be expressed as i = I m. sin(ωt – φ).
LCR Series Circuits Learn About Electronics
Fig 9.1.4 illustrates the phasor diagram for a LCR series circuit in which X C is greater than X L showing that when V C exceeds V L the situation illustrated in Fig 9.1.3 is reversed.. The resultant reactive voltage is now given by (V C − V L) and V S is the phasor sum of (V C − V L) and V R.. The phase angle θ now shows that the circuit current (I S) leads supply voltage (V S) by ...
