Why L and C are connected in parallel in a LC filter?
Alishashenoy94
LC are connected in parallel combination to short out signals too high or too low in frequency from getting to the load.
FYI:
Series LC circuits give minimum impedance at resonance, while parallel LC (“tankâ€) circuits give maximum impedance at their resonant frequency.
The LC circuit behaves as an electronic resonator, which are the key component in many applications. Oscillators Mixers Graphics tablets Filters Electronic article surveillance & Tuners
For example: a capacitor/inductor oscillator acts as the tuner for the radio.
The sine wave that matches that particular frequency will get amplified by the resonator, and all of the other frequencies will be ignored. In a radio, either the capacitor or the inductor in the resonator is adjustable. This is how you "tune in" different stations on the radio :)
In a nutshell: A series resonant circuit provides voltage magnification and a parallel resonant circuit provides current magnification.

∙ 9y agoThe L and C are connected parallel because it determines the instructor. This is on a LC filter.

What is a LC?
LC means a circuit contain capacitor(C) and inductor(L). They are connected in series. L is inductance, units is Henry(H). C is capacitance, units is Faraday(F) don't have battery.
If two identical capacitors connected parallel then effective capacitance?

Why capacitor connected in parallel in circuit?
Any answer "why" will depend on the rest of the circuit, which may an electric motor, a filter, or any number of other applications.If you're asking about 2 or capacitors in parallel, it is to provide a higher capacitance, since the total C will be the sum of each device's individual capacitances.Ctotal = C1 + C2 + C3 ...+ CnConversely capacitors in series obey the reciprocal law:1/Ctotal = 1/C1 + 1/C2 + 1/C3 ...+ 1/Cn

Where is the LC Circuit located?
The LC circuit, or tank circuit, is most commonly located in radios. Its function is to tune radio transmitters to a specific station. The LC circuit consists of an inductor (L), and a capacitor(C), hence the term, LC 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.
What are the Difference between RC oscillator And LC oscillator?
The difference between an RC and LC is that the frequency - determining device in the RC oscillator is not a tank circuit. LC can operate with A or C biasing, while RC can only operate with A.

Three identical bulbs are connected in series labeled A B and C to a battery which bulb is the brightest?
If three identical bulbs are connected in parallel to a battery, all three bulbs would have equal brightness.Kirchoff's voltage law states that the signed sum of the voltage drops around a series circuit is zero. A consequence of this is that, in a parallel circuit, the voltage across each parallel element is the same.There are effectively 6 series circuits in this example - battery and A - battery and B - battery and C - A and B - A and C - and B and C. These six combinations are also parallel circuits, and they are also in parallel with each other.
