Reading time: 6 minute A capacitor and a coil connected together form an oscillating circuit, which resonates (oscillates) on a certain frequency. At this frequency, the energy is transferred from the capacitor to the coil and vice versa in the form of voltage and alternating current, out of phase with each other by 90 degrees.

Reading time: 6 minute Light emitting diodes are almost everywhere. They can be found in cars, bicycles, street lighting, at the office, in mobile phones, televisions and much more. The reason for such a wide range of LED applicability is the advantage over traditional incandescent bulbs and recent compact fluorescent lamps (CFLs).

Reading time: 6 minute The amplitude of a waveform in alternating current is practically a value that is calculated on the graph, depending on the time and height of the signal. For alternating current signals we have several types of amplitude calculations such as: peak value, peak to peak amplitude, average amplitude, effective value (RMS).

Reading time: 5 minute In alternating current, voltage and current change their polarity; the direct current maintains the voltage and the current at a polarity, respectively a constant direction in time; Alternating current electromechanical generators, known as alternators, are much easier to build than direct current generators. The same is true for electric motors.
