ek 750-kΩ pratirodh, jo ki ilektraanik varn koot dvaara pahachaana jaata hai. vaise ise ohmameetar dvaara bhi padha ja sakta hai.

vidyut pratirodh vah anupaat hai, jis koti tak swayam se jaane vaale vidyut dhaara ka virodh karta hai. ise ohm mein maapa jaata hai. iski pratilomeeya maatra hai vidyut chaalakata, jiski ikaai hai saaimans. samaan dhaara ghanatv maanate hue, kisi vastu ka vidyut pratirodh, usaki bhautik jyaamiti aur vastu ki pratirodhakata ka prakaarya hai:

jahaan

"l" usaki lambaai hai
"A" anuprasth parichhed kshetrafl hai aur
"ρ" vastu ki pratirodhakata hai

ise George ohm ne 1820 ke ant mein khija tha.[1], vidyut pratirodh yaantrik gharshan ke kuchh kuchh samatulya hai. iski SI ikaai hai ohm (chinh Ω). kisi vastu ka pratirodh us vastu se bahne vaale vidyut dhaara ki maatra tay karta hai, jabaki us vastu ke chhoron ka vibhvaantar samaan rahe.

jahaan

R vastu ka pratirodh hai, jo ohm mein maapa gaya hai, J·aas/C2ke tulya
V vastu ke aar-paar ka vibhvaantar hai, volt mein maapa gaya.
I vastu se hokar jaane waali vidyut dhaara hai, empeeyr mein maapi gayi.

bahut saari vastuon mein, pratirodh vidyut dhaara ya vibhvaantar par nirbhar naheen hota, yaani unka pratirodh sthir rahata hai.
