Parallel Resonance Circuit
The frequency response curve of a parallel resonance circuit shows that the magnitude of the current is a function of frequency and plotting this onto a graph shows us that the response starts at its maximum value, reaches its minimum value at the resonance frequency when I MIN = IR and then increases again to maximum as ƒ becomes infinite.. The result of …

Harmonic resonance in power systems
It is often difficult to predict which capacitor installations will be troublesome, particularly when there are numerous capacitors and harmonic-producing loads scattered over a plant''s power system.

Parallel Resonance
This example shows parallel resonance.The three circuits have the inductor, resistor, and capacitor in parallel instead of series. In this case, the middle circuit is being driven at resonance, which causes the current there to be lower than in the other two cases (because the impedance of the circuit is highest at resonance).

Parallel Resonance
The current flowing through the capacitor and the coil is much greater than the line current because the impedance of each branch is quite lower than that of circuit impedance Zr. Since the parallel resonant circuit can draw a very small current and power from the mains, therefore, it is also called as Rejector Circuit.

Resonance
Resonance occurs when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a simple pendulum). However, there are some losses from cycle to cycle, called damping.When damping is small, the resonant frequency is approximately equal to the natural frequency of the system, …
CIRCUITS LABORATORY EXPERIMENT 5
The capacitor, C, is assumed to be lossless. This is not strictly true, and, indeed, just as for an inductor a Q value could be ascribed to a capacitor to account for its loss. However, a capacitor of reasonable quality can easily have a Q value exceeding several hundred and so for simplicity we will neglect any capacitor loss here.

Difference between Series Resonance and Parallel Resonance
Answer: A Parallel Plate Capacitor is a capacitor with two parallel conducting plates separated by an insulating material and capable of storing electrical charge. Capacitance can be defined in Layman''s terms as a physical quantity that indicates the ability of a component or circuit to collect and store energy in the form of an electrical charge.
Harmonic resonance calculation in power-factor correction
Since the capacitor and transformer impedances are based on the relevant power frequency, that frequency is the fundamental for the harmonic order calculation. On other words, the formula is valid for either 50 or 60 Hz as long as the capacitor bank VAR rating and the short circuit VA are stated or calculated based on the frequency of interest.
What are impedance/ ESR frequency characteristics in capacitors?
The multilayer ceramic capacitor and leaded film capacitor show roughly the same characteristics up to the resonance point, but the self-resonant frequency is higher and |Z| in the inductive region is lower in the multilayer ceramic capacitor. This is because, in leaded film capacitors, the inductance is only as large as that due to the lead wire.

Resonance Explained
In electric circuits, there are energy-storing elements like capacitors and inductors. The energy-storing elements are what cause resonance. Resonance is the driving concept behind the working principle of TV and radio receivers, allowing viewers to select desired frequencies for their TV channels.. Image used courtesy of Adobe Stock.
