# Effect of resonance in electrical systems & circuits

• posted

Does anybody have any experience on resonance in electrical systems & circuits. What is its effect and what causes it.

Thanks Anton

Anton, you either need to narrow your question down or take a course in AC fundamentals.

A very wide open question indeed. Any alternating or switching system will create resonance, vibration and magnetic fields of some sort in a circuit, so you'd really need to narrow down, quite a bit, on which types of electrical and electronic systems you wish to study.

Electro-Magnetic Fields are always present in any electron flow through a conductor or device, some are designed in to the system, some need to be removed from systems where they can cause unwanted side effects.

As others have implied, you have eyes bigger than your stomach. Nevertheless, if you want to understand resonance in your gut as opposed to your mind, you may be better off thinking mechanically in terms of pendulums, vibrations of musical instruments, and shimmy in automobiles.

A component which stores energy can interact with other energy storage components. Sometimes, very large swapping of energy can occur, often when there is stimulation at or near a 'resonant' frequency. Go push up and down on your car's bumper. At certain frequencies (resonant frequencies) you can really get the car hopping with relatively little pushing. Here I guess the energy storage components would be the springs (which store energy when extended or compressed out of their 'relaxed' length) and the mass of the car (which stores energy as kinetic and/or gravitational energy). In electric circuits, energy storage components are often capacitors (or capacitances, such as line to ground capacitance of a cable or transmission line) and inductors (or inductances, such as self and mutual inductance of conductors, and magnetizing and leakage inductances of motors and transformers).

Do you have a specific application in mind where you are wondering about cause and effect? Electronics? Harmonics? Switching?
