Why does a series resonant circuit cannot be tank circuit?
A series resonant circuit has it's reactive components connected in series with each other; while the reactive components, as in a "tank" circuit, are connected in parallel with each other. The resonant series circuit has the capability of producing usable increased voltage levels across each component at resonance, while the resonant tank circuit does not. The resonant parallel, or "tank" circuit; has the dual capability of creating a situation whereby the input amperage level is reduced to minimum while, at the same time, a maximum amount of circulating amperage is created between the two reactive tank components at resonance.
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
How does a RC tank circuit work?
A tank circuit is an LC filter that, when at resonance, has an near infinite resistance. It is composed of an inductor in parallel with a capacitor. Resonance occurs when the magnitude of the impedance of the cap and inductor are equal. They have a fairly narrow bandwidth, which is why they are used in RF applications. They are able to 'focus in' on the desired frequency, and ignore the others. For example, if I have a simple tank circuit with a resonant frequency at 1 MHz connected to an unregulated ac function generator, and I measure the voltage across the tank circuit, when the frequency I apply is close to the resonant frequency, the amplitude of my output begins to increase. So at 900kHz, say, I might be getting 90% of the signal I apply to the circuit as my output. The impedance of this circuit increases as the frequency nears the resonance frequency of the tank. So if I set the function generator to 1MHz, the tank has extremely high impedance, and functions like an open, so I can expect my entire signal to drop across the tank circuit. Alternately, they can be used to create oscillators. Another name for a tank circuit which more useful for visualizing how it functions is the slosh circuit. When energy is applied to the slosh circuit, the cap will discharge into the inductor, and vise versa, and it will oscillate like this at the tanks resonant frequency. The energy 'sloshes' from one component to the other. This can be exploited by circuitry to make oscillators, amplifiers, voltage doublers and so on. I have not seen an RC tank circuit before, but one is theoretically possible using an active circuit called a gyrator, which consists typically of an op amp, a couple resistors, and a capacitor. A gyrator essentially makes one component function like another. If I construct a gyrator with a cap, it will function much like an inductor (not identically, there are a few differences), and likewise, I could make a psuedo-cap using an inductor based gyrator. So one could conceivably make a tank circuit using this gyrator in place of an inductor. But as far as practicality goes, I'm not sure how good of a substitute it would make, as the gyrator doesn't exhibit all of the properties of an inductor, and some active components can be quite sensitive to voltage, and extreme voltages are possible in a tank circuit configuration due to opposing phase shifts from the components. And, just to be pedantic, it would probably be called an RCQ tank circuit.
What is reactance?
The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.

When a parallel LC circuit is tuned to resonance will the current be at a maximum or a minimum?
Inside the circuit loop between the inductor and capacitor the current will be at maximum. Outside the circuit the current through the LC tank circuit will be at minimum. It depends on where you are measuring it.
What are all the types of circuits?
Series circuit Parallel circuit Tank circuit
Parallel tuned circuit in resonance frequency?
A parallel resonant circuit has at its heart an inductorand a capacitor. These are the two parallel components. They each react to voltage and current 180 degrees out of phase with each other. When we "hit" this circuit, called a parallel tank circuit, or just a tank, with voltage, one component is "putting energy into the circuit" while the other one is "storing it up" and then the two components switch roles. The result is that the tank will oscillate, and the frequency of oscillation will be determined by the value of the capacitor and the inductor.
Can electricity flow through a parallel circuit?
'Electricity' is the name given to a branch of science; it is NOT a quantity. So your question should read, 'How does an electric current flow through a parallel circuit?'The answer is that a parallel circuit is made up of two or more individual 'branches'. The sum of the currents flowing through each branch is the value of the current being drawn from the supply by the complete circuit.
Why you use parallel resonance circuit instead of series resonance circuit in tuned voltage amplifier?
At resonance...a parallel tank circuit matches the applied sine voltage so close that there is almost 0 current flow from the source...i.e., max impedance at resonance...the capacitor and inductor are swapping energy with each other in tune with the source... visualize it...in order to have 0 current flow for an incoming varying voltage...that would mean that the tank voltage would be varying exactly at the same frequency and voltage! Thus...you have effectively "tuned" into a voltage which would be critical in 'tuned' voltage amplifier... A series resonant circuit does not tune into a voltage...in fact at resonance the voltage across the inductor capacitor will be 0!...a short or minimum impedance condition Of course my discussion assumed ideal components...in the real world there will be 'stray' resistances which will alter the results in magnitude to the size of the resistance... Hope this helps

What is meant by tank circuit in hartley oscillator?
it is the circuit that is responsible for producing oscillation.In hartley it is two inductors connected in series and a capacitor parallel to this series connection.Without tank oscillator tends to act as as an amplifier.

Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
What is a tank circuit used for?
A tank circuit is used on a radio transmitter. It is an electronic circuit that is used to tune a specific frequency. The tank is made up of two components, an inductor and a capacitor. The two components are connected in a parallel with each other. This is where the term "tank" comes from. Used in a radio transmitter, it is tuned for maximum RF (radio frequency) output on the frequency the transmitter is tuned to.
