What is the definition of series and parallel resonant circuits?

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.
At a frequency below the resonant frequency parallel circuit is?
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
Series resonance circuit is also known as acceptor circuit why?
Because the series resonant circuit has the lowest possible impedance at resonance frequency, thus allowing the AC current to circulate through it. At resonance frequency, XC=XL and XL-XC = 0. Therefore, the only electrical characteristic left in the circuit to oppose current is the internal resistance of the two components. Hence, at resonance frequency, Z = R. Note: This effect is probably better seen with vectors. Clarification: Resonant circuits come in two flavors, series and parallel. Series resonant circuits do have an impedance equal to zero at the resonant frequency. This characteristic makes series resonant circuits especially well suited to be used as basic pass-band filters (acceptors). However, parallel circuits present their maximum impedance at the resonant frequency, which makes them ideal for tuning purposes.
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 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
Why parallel resonance circuit is called tank circuit?
traditionit is often used (like a storage tank for water is) to store resonant energy in AC circuits.
Can a series resonant circuit oscillate as a parallel resonant circuit does?
yes
At a frequency below the resonant frequency parallel circuit is?
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
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.

Explain the use of a varactor diode in a parallel resonance circuit?
Short answer: By using a varactor diode as the capacitance in a parallel resonant ckt, by changing the reverse bias voltage you change the value of capacitance which in turn changes the resonant frequency. This makes a tuneable resonant ckt.
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.
Why a parallel resonant circuit is called as rejecter circuit?
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
What is the function of varactor diode?
Voltage controlled variable capacitor. Usually used for dynamic tuning of resonant circuits.
