2. Electrosurgery - Wikipedia

   en.wikipedia.org/wiki/Electrosurgery

   Electrosurgery. A surgeon using a monopolar RF electrosurgical instrument to coagulate (and desiccate) tissue in the excision of a lipoma. MeSH. D004598. [ edit on Wikidata] Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate ...

3. Skin effect - Wikipedia

   en.wikipedia.org/wiki/Skin_effect

   Skin effect. Distribution of current flow in a cylindrical conductor, shown in cross section. For alternating current, current density decreases exponentially from the surface towards the inside. Skin depth, δ, is defined as the depth where the current density is just 1/e (about 37%) of the value at the surface; it depends on the frequency of ...

4. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   e. A thermoelectric generator ( TEG ), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect ). Thermoelectric generators function like heat engines, but are less bulky and ...

6. Blocking oscillator - Wikipedia

   en.wikipedia.org/wiki/Blocking_oscillator

   Blocking oscillator. Basis of solid-state Blocking oscillator. The waveform generated by this circuit. This Joule thief circuit, a blocking oscillator, can be used in order to power a light-emitting diode from a 1.5V battery for a relatively long period of time, with the brightness being a tradeoff.

7. Electrostatic generator - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_generator

   12" Quadruple Sector-less Wimshurst Machine (Bonetti Machine) An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained ...
