What is resonance in LC circuit?

The total current in the circuit is split between these two components, depending on their characteristics. In an LC circuit, resonance is a special condition that occurs when the energy stored in the inductor and the capacitor is perfectly balanced, causing the circuit to oscillate at a particular frequency.

What is the admittance of a series resonant circuit?

Therefore, at the resonance frequency ω 0, the imaginary part of Y in (2.20) must vanish, that is, ω 0C −1/ω 0L = 0, which gives for the resonance frequency which is identical to the resonance frequency for a series resonant circuit as given by (2.18). The admittance at resonance is therefore Y = 1/ R.

What is the resonant frequency of an LC circuit?

In an LC circuit, the resonant frequency f0 is the frequency at which the inductive reactance equals the capacitive reactance. At this frequency, the voltages across the inductor and capacitor are equal and opposite in sign.

Why is a LCR circuit resonant?

the total impedance is minimised the circuit is said to be in resonance. The resonant behaviour of LCR circuits has many important applications in modern communications and is analogous to resonancephenomena observed in other branches of physics, such as in mechanical systems and in atomic and nuclear physics. In th

What is RLC resonance?

Resonance of an RLC circuit occurs when the voltage across the inductor is the same as the voltage across the capacitor, or V_L = V_C. As a result, the EMF of the battery is entirely consumed by the resistor and the current achieves its maximum value. The basic condition for resonance can be easily derived.

Can a series resonant circuit suppress noise?

After that, a case where noise was suppressed by using a series resonant circuit of a capacitor and an inductor was reported. However, it had no means to control the output voltage, and had the problem that fluctuations in the input voltage would directly cause fluctuations in the output.
