  K\u0101 darbojas EDM: Zin\u0101tne, kas sl\u0113pjas aiz dzirksteles<\/h2>

  EDM balst\u0101s uz trim pamatkomponentiem:<\/p>

  1. Elektrodi<\/strong>: Dzirksteles rada r\u012bks (sinker) vai stieple.<\/li>
  2. Dielektriskais \u0161\u0137idrums<\/strong>: Izskalo gru\u017eus un atdzes\u0113 apstr\u0101d\u0101jamo deta\u013cu (e\u013c\u013ca vai dejoniz\u0113ts \u016bdens).<\/li>
  3. Baro\u0161anas avots<\/strong>: Izraisa straujas elektrisk\u0101s izl\u0101des (l\u012bdz 100 000 dzirkste\u013cu sekund\u0113).<\/li><\/ol>
