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.


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.


Uses of gang capacitor?

Gang capacitors are commonly used in radio tuners/receivers. Radio tuners/receivers have formation of LC(inductance and capacitor). Here this circuit has one fixed inductance and capacitor parallel with gang capacitor. Normally gang capacitor used in superhetrodyne receiver.


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.


What is the advantage of capacitor filter over inductor filter?

An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter


What is the difference between LC and RC filters?

LC means coil capacitance circuit RC means resistance capacitance circuit


What is the use of gang capacitor in the field of embedded system?

Gang capacitor is used along with an inductor coil(L) in a LC circuit to tune to a particular frequency which is to be received. The frequency of a LC combination is given by the formula f=1/(2*pi*L*C). here f is the frequency to be received. L is the inductance. C is the capacitance. The capacitance(C) of the Gang capacitor can be varied to tune to different frequencies. I recently made my college project in which I used Gang capacitor in a FM receiver circuit. The received signal was decoded and sent to a micro-controller and then to a computer. I hope this is of sm help to u! VISHESH Delhi, India.


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.


Why doesn't LC circuit exist?

even though a resistance is not connected in a circuit, it would practically have small resistance due to its components.so practically a LC circuit dosent exist..only a RLC circuit exists


How does the turn off circuit on a Class B type thyristor work?

The Class B type of commutation circuit uses an LC circuit in parallel with the thyristor. During initial power up, the capacitor C charges to the supply voltage (Edc) and the thyristor is OFF. The initial charging current of the LC branch flows thru the load. When the thyristor is fired, the supply DC voltage is applied across the load, and the voltage across the LC branch goes to almost zero (the forward drop of the thyristor). Then the LC circuit enters a resonant discharge with an angular frequency of the square root of the inverse of LC product. The LC resonant cycle supplies a peak forward current thru the thyristor of Edc times the square root of C/L. This peak current must exceed the load current in order to effect the turn-off of the thyristor during the second half of the discharge resonant cycle. This peak current is usually designed to be twice the load current. The thyristor is reversed biased (and turned OFF) during the first quarter cycle of this second half of the resonant cycle - thus allowing the supply to recharge the capacitor in the LC parallel branch. Then the cycle can repeat.


Are LC circuits and tuned circuits same thing?

a "LC circuit at resonance" and tuned circuits are the same
