The current through a resonant circuit is (in general) out of phase with the voltage. One measure of the phase angle is this angle. At resonance the phase angel is near zero so it can be used as a parameter to drive a self-tuning mechanism.

What is the use of series and parallel resonance?
Series resonant circuits have their lowest impedance at the resonant frequency. Parallel resonant circuits have their highest impedance at the resonant frequency. This characteristic is exploited in the design of filters, oscillators and other circuits.
What is the definition of series and parallel resonant circuits?

How do you shift an ac phase?
It really does depend upon what you mean by 'shift'. For purely-resistive circuits, the load current is in phase with the supply voltage. For reactive circuits, the load current will lead or lag the supply voltage; for capacitive-resistive circuits, the load current leads, whereas for inductive-resistive circuit, the load current lags. You can change the angle by which the current leads or lags (the 'phase angle') by changing the amount of resistance or reactance.
What do you understand by bandwidth of a parallel resonant circuits?
The bandwidth of a resonant circuit is defined as the distance between the two -3dB rolloff points in the response curve.
What is a tuning capacitor?
A capacitor whose capacitance is variable (within some range). They are usually used to adjust resonant circuits or delay circuits.

What do you mean by resonant in power electronics?
Resonant in electronics circuit refer to tuning if the resonant condition arise it means the frequency where does the resonant arise is resonant frequency and the gain is highest on that particular frequency. it is widely used in receiver circuits.

What are the applications of single tuned coupled circuits?
The resonance effect of the LC circuit has many important applications in signal processing and communications systems.The most common application of tank circuits is tuning radio transmitters and receivers. For example, when we tune a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.A series resonant circuit provides voltage magnification.A parallel resonant circuit provides current magnification.A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.Both parallel and series resonant circuits are used in induction heating.LC circuits behave as electronic resonators, which are a key component in many applications:AmplifiersOscillatorsFiltersTuners

What is phase angle in ac?
It's the amount by which voltage leads current (or vice versa) in the AC circuit. By convention, the phase angle is positive in inductive circuits (where voltage leads current) and negative in capacitive circuits (where current leads voltage).AnswerUnfortunately, the original answer has things the wrong way around. By definition, phase angle is the angle by which the current leads or lags the supply voltage (not the other way around). Therefore, the phase angle is considered negative (current lagging) for an inductive circuit, and positive (current leading) for a capacitive circuit. This is because, for a phasor diagram, counterclockwise is the positive direction, whereas counterclockwise the the negative direction.
What is the code ruling in the US on 3 phase branch circuits and the neutral?
A three phase system will have 3 phase branch circuits and no neutral.
What is the function the capacitor in electronic board?
Dozens of functions. Short term power storage. Smoothing. Decoupling, Coupling, Voltage doubling. Resonant circuits. Phase shifting. Timing circuits. Delay circuits. Lumped constant delay lines as used in radar modulators. And many more...I even used one once as a poor man's one bit RAM.
What is the function of varactor diode?
Voltage controlled variable capacitor. Usually used for dynamic tuning of resonant circuits.
