Ringa mabviro eMukweso

[[Image:Metal_film_resistor.jpg|thumb|250px|Chiromukweso (resistor), sekuzikanwa kubva pakodhi yemavara yezveugetsi (electronic color code) (blue–green–black-gold). Ohmita inogona kushandiswa kunyatsozivisa kuti chiremo ichi ndechemachokwadi here.]]

'''Mukweso wemagetsi''' (muChirungu: electrical resistance) wechinhu chinoshanda nemagetsi zvinoreva kupikisa kwekufamba kwe[[muyerero wemagetsi]] muchinhu ichocho. Kana mukweso wakondekwa (inverse) unonzi [[Mugwinho|mugwinho]]; izvi zvinoreva kuti zviri nyore sei kuti [[muyerero wemagetsi]] upfuure muchinhu chinoshanda nemagetsi. Chiyerwo chemukweso mu[[Dandira reZviyero Pasirose|dandira rezviyero pasirose]] (SI) chinonzi [[ohm]]. Mugwinho hunoyerwa muma[[siemens]].

Chiro chine [[mucheko wenharaunda]], wakaenzanirana chinoratidza [[mukweso]] une [[rupandavaro rwakadondeka]] [[hurefu]]. Zvinhu zvese zvine mukweso wemagetsi, kunze kwemasupakondakita asina mukweso.

Mukweso (R) wechiro unodudzirwa semudida we[[basa paumwe hwechaji]] (vhoruteji) kumativi kwechiro (V) nerufuvha muchiro ichocho (I) pachiva nemugwinho (G) iri pindukwo yacho:

:<math>R = {V\over I}, \;\;\;\;\; G = {I\over V}</math>

Kune zviro zvizhinji, '''V''' na '''I''' zvine [[rupandavaro rwakadondeka]]; izvi zvoreva kuti '''R''' na '''G''' [[mikokonerwa]] '''(constants)''' (asi zvinogona kushanduka zvichienderana nezvimwe zvinhu somuenzaniso, hujoto). [[Rupandavaro]] urwu runodudzirwa ne[[Mutemo waOhm]] uye zviro zvinotaridza rupandavaromsaizvozvi zvinonzi [[zviro zviri ohmiki]].

Mukweso wemagetsi unoyerwa ne'''ohmita''' (ohmmeter).

Rimwe izwi rinoreva '''resist''' nderekuti [[kutayira]], [[kutavira]].???
