Bir elektrik devresinde; Ak\u0131m, Voltaj ve Diren\u00e7 aras\u0131nda bir ba\u011flant\u0131 mevcuttur. Bu ba\u011flant\u0131y\u0131 veren kanuna Ohm kanunu ad\u0131 verilir. <\/p>\n
1827 y\u0131l\u0131nda Georg Simon Ohm \u015fu tan\u0131m\u0131 yapm\u0131\u015ft\u0131r: <\/p>\n
\u201cBir iletkenin iki ucu aras\u0131ndaki potansiyel fark\u0131n\u0131n,iletkenden ge\u00e7en ak\u0131m
\n \u015fiddetine oran\u0131 sabittir.\u201d <\/p>\n
R = V \/ \u0130 ( 1 )
\n V = \u0130 x R ( 2 )
\n \u0130 = V \/ R ( 3 ) <\/p>\n
\u015feklinde ifade edilir. Burada R diren\u00e7tir. Bu diren\u00e7 resistans veya empedans olabilir. V volttur. \u0130 de ak\u0131m yani Amperdir. <\/p>\n
Su dolu bir depo olsun, bunun dibine 5 mm \u00e7ap\u0131nda bir delik a\u00e7al\u0131m, bir de 10 mm \u00e7ap\u0131nda bir delik a\u00e7al\u0131m. B\u00fcy\u00fck delikten daha \u00e7ok suyun akt\u0131\u011f\u0131n\u0131 yani bu deli\u011fin suyu daha az engelledi\u011fini g\u00f6r\u00fcr\u00fcz.
\n Burada deli\u011fin engellemesi dirence, akan suyun miktar\u0131 ak\u0131ma, depodaki suyun y\u00fcksekli\u011fi voltaja kar\u015f\u0131l\u0131k gelir. <\/p>\n
Elektrik devrelerinde de, bir gerilimin kar\u015f\u0131s\u0131na bir diren\u00e7 koyarsan\u0131z, direncin m\u00fcsaade etti\u011fi kadar elektron ge\u00e7ebilir, yani ak\u0131m akabilir, ge\u00e7emeyen iti\u015fip duran bir k\u0131s\u0131m elektron ise, \u0131s\u0131 enerjisine d\u00f6n\u00fc\u015f\u00fcr ve s\u0131cakl\u0131k olarak kar\u015f\u0131m\u0131za \u00e7\u0131kar. <\/p>\n
Diren\u00e7 birimi \u201cOhm\u201cdur bu de\u011fer ne kadar b\u00fcy\u00fck ise o kadar \u00e7ok
\n diren\u00e7 var anlam\u0131na gelir.<\/p>\n","protected":false},"excerpt":{"rendered":"
