Umxholo wombane wangoku

Kwi-Electromagnetism, isixa sombane esigqitha ngalo naliphi na icandelo lezithuthi kwicandelo ngalinye leyunithi libizwa ngokuba yingqongqo yangoku, okanye yombane kuphela. Isimboli sangoku se-I, kwaye iyunithi i-Ampere (A), okanye "arré-marie Amps, i-French Ample Amputer, i-French, inikwe iNtengiso.

[2] Kumbane, icacisiwe ukuba umkhombandlela wendlela yokuhamba kwezikhokelo kwezityholo ezilungileyo. Ukongeza, kubunjineli, ulwalathiso oluhamba ngokuhamba kwezikhokelo ezihamba ngezityholo ezilungileyo zisetyenziswa njengelizwi langoku. Ubungakanani bexesha elibonisiweyo yintlawulo ye-q equkuqela kwicandelo lomnqamlezo womqhubi wexesha ngalinye leyunithi, ebizwa ngokuba yingqongqo yangoku.
[3] Zininzi iindidi zabathwali kwindalo ephethe intlawulo yombane. Umzekelo: I-elektroni ezinokususwa kwabaqhubi, ii-Ion kwi-electrolyte, elektroni kunye nee-ions kwiplasma, kunye ne-quarks kwi-hadrons. Ukuhamba kwaba bantu bathwala bukhona kwangoku.
