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

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

    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.

    A little more specific please.

    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

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