Kusiyana Kwakukulu pakati pa kuyatsa kwamagetsi otsika ndi kuyatsa kwamagetsi apamwamba.

Kusiyana kwakukulu pakatinyali zotsika mphamvundi nyali zamphamvu kwambiri ndikuti amagwiritsa ntchito mitundu yosiyanasiyana yamagetsi. Nthawi zambiri, ma voltage otsika ndi omwe amayendera pamagetsi otsika a DC (nthawi zambiri 12 volts kapena 24 volts), pomwe ma voltage okwera kwambiri ndi omwe amayendera 220 volts kapena 110 volts ya mphamvu ya AC.

Nyali zotsika kwambiri zimagwiritsidwa ntchito powunikira m'nyumba, kuunikira kwa malo ndi zochitika zina zomwe zimafuna kuunikira kokongoletsera kapena pang'ono, monga nyali za xenon, nyali za LED, nyali za halogen, ndi zina zotero. Koma imafunikanso mphamvu yowonjezera yotsika kwambiri (transformer, etc.) kuti itembenuke, zomwe zimawonjezera mtengo ndi zovuta.

Nyali zamphamvu kwambiri zimagwiritsidwa ntchito pakuwunikira kwakukulu, kuunikira kunja ndi zochitika zina zomwe zimafuna kuunikira kosiyanasiyana, monga magetsi a mumsewu, magetsi apamtunda, magetsi a neon, ndi zina zotero. Koma palinso zoopsa zomwe zingachitike panthawi imodzimodzi, monga kugwedezeka kwamagetsi. Kuphatikiza apo, mababu a nyale zamphamvu kwambiri amakhala ndi moyo waufupi ndipo nthawi zambiri amafunika kusinthidwa.

Choncho, posankha nyali, m'pofunika kuganizira zinthu zosiyanasiyana monga kuyatsa kofunikira, malo a malo, ndi zofunikira za chitetezo, ndikusankha nyali yoyenera yotsika kwambiri kapena yamagetsi.
