charging of a capacitor
101Car audio — Car audio/video (car AV), auto radio, mobile audio, 12 volt and other terms are used to describe the sound or video system fitted in an automobile. While 12 volt audio and video systems are also used, marketed, or manufactured for marine,… …
102Defibrillation — View of defibrillator electrode position and placement. Defibrillation is a common treatment for life threatening cardiac arrhythmias, ventricular fibrillation and pulseless ventricular tachycardia. Defibrillation consists of delivering a… …
103Evanescent wave — Schematic representation of evanescent waves propagating along a metal dielectric interface. The charge density oscillations, when associated with electromagnetic fields, are called surface plasmon polariton waves. The exponential dependence of… …
104Automated external defibrillator — An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,cite… …
105Single-wire earth return — (SWER) or single wire ground return is a single wire transmission line for supplying single phase electrical power from an electrical grid to remote areas at low cost. It is principally used for rural electrification, but also finds use for… …
106Opto-isolator — This article is about the electronic component. For the optical component, see optical isolator. Schematic diagram of an opto isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on… …
107Electret — (formed of elektr from electricity and et from magnet ) is a dielectric material that has a quasi permanent electric charge or dipole polarisation. An electret generates internal and external electric fields, and is the electrostatic equivalent… …
108Voltage-controlled oscillator — A voltage controlled oscillator or VCO is an electronic oscillator designed to be controlled in oscillation frequency by a voltage input. The frequency of oscillation is varied by the applied DC voltage, while modulating signals may also be fed… …
109Voltage regulator — A popular three pin 12 V DC voltage regulator IC. A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple feed forward design or may include negative feedback …
110Flyswatter — A flyswatter is a hand held device for swatting flies and other insects.Though the modern flyswatter usually just usually consists of a small rectangular sheet (about 4 inches or 10 cm across) of lightweight, flexible, vented material, usually… …
