Parallel Resonance Circuit Basic Electronics Tutorials

Since the current flowing through a parallel resonance circuit is the product of voltage divided by impedance, at resonance the impedance, Z is at its maximum value, ( =R ). Therefore, the circuit current at this frequency will be at its minimum value of V/R and the graph of current against frequency for a parallel resonance circuit is given as.

How Do You Find The Resonance Frequency of A Rock ...

Jan 21, 2014· To find the resonant frequency, hook up a microphone to an oscillocope, ping the rock with a hammer, and the sillyscope will display it's resonant frequency. Then match that frequency with a frequency generator and an amplifier. You can build your own frequency generator with many IC's (EX: CD4069) using RC to set frequency.

PAVEMENT TECHNOLOGY ADVISORY RUBBLIZING PTAM1

A Resonant Frequency Breaker uses a highfrequency, low amplitude striking force to break the concrete. The breaker head covers a small area, requiring up to 20 passes per lane to cover the pavement width. Since one side of the machine travels on rubblized concrete, deformation of the underlying base or subgrade may occur.

LC circuit Wikipedia

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected circuit can act as an electrical resonator, an electrical analogue of a tuning fork, storing energy oscillating at the circuit's resonant frequency.

failure due to resonant excitation. Resonant vibration caused 50 of the 124 spans of the Viaduct to collapse. The reinforced concrete frames of those spans were mounted on weak soil. As a result, the natural frequency of those spans coincided with the frequency of the earthquake ground motion. The Viaduct structure thus amplified the ground motion.
