Sažetak

Cilj istraživanja bio je merenje električnih osobina perge. Izmereni su kapacitivnost, otpornost, impedansa. Svako svojstvo mereno je na svim frekvencijama tri puta. Prosečna vrednost i standardna devijacija i izračunati su iz ovih merenja. Otpornost, impedansa i kapacitivnost smanjuju se frekvencijom u skladu sa funkcijom snage. Impedansa ima nešto veću vrijednost kao otpornost, što je uzrokovano kapacitivnošću perge. Utvrđeno je da se dielektrična konstanta perge povećava kada se vlažnost perge povećava. Minimalno smanjenje je na višim frekvencijama. Merenja ukazuju na to da perga treba da bude svrstana u organske heterogene viškomponentne dielektrike ili poluprovodnike.
