Pavel Nikolayevich Jablotschkow (Russian Павел Николаевич Яблочков; * 2 Septemberjul / September 14 1847greg in Serdobsk in Saratov, Russia, .. .. † 19 Märzjul / March 31 1894greg in Saratov ) was a Russian engineer and inventor.

Jablotschkow studied at the St. Petersburg Military engineering University of Engineering Sciences and Physics. After working in the military service, he worked in the telegraph system and dedicated to electrical engineering research.

Among others, he dealt with the problem, a - to ensure constant electrode spacing at the then carbon arc lamps - despite the constant erosion of the electrodes. In 1875 he presented his simple solution: he ordered the carbon electrodes parallel to each other and separated them by an insulating layer, which burned to the electrodes. The so-called " Jablotschkow'sche candle " he had patented in 1876 in Paris and produce on an industrial scale. He also dealt with the economic use of its lamps in larger lighting systems.

In 1879 he started his own business with a company for electric lighting systems and also worked on improving several electrical devices such as dynamos and accumulators. He presented his products in all major exhibitions of his time in Russia and elsewhere in Europe. Jablotschkowschen the candles were replaced by invented by Friedrich von Hefner - Alteneck differential arc lamp. Against the emergence of powerful competition in the field of lighting systems ( differential arc lamp by Siemens and Edison light bulb ) is Jablotschkow could no longer prevail.

End of the 80s of the 19th century developed Jablotschkow an electric mobility scooter A. flakes of the first car is one next to the electric car of the German machine factory with electric drive.
