Voltage ndi imodzi mwa zinthu zomwe zimachitika tsiku ndi tsiku zomwe zimakhala zosalephereka. Timangokhalira kutsegula magetsi kuti tiyatse magetsi kapena kusindikizira makatani kuti muyambe kugwiritsa ntchito zipangizo zonse, popanda kuzipereka zambiri. Magetsi ali paliponse, ndipo nthawi zonse akhala akutero kwa ambiri a ife. Koma mukadzipereka nokha kamphindi kuganiza, mungadabwe za mphamvu izi zonse padziko lonse lapansi. Zingamveke zosawerengeka, koma mpweya ndi wosavuta kumvetsa monga chidebe cha madzi.
Tanthauzo ndi Ntchito
Mphamvu imatanthawuza ngati mphamvu yamagetsi kapena mphamvu yamagetsi yosiyana mphamvu pakati pa mfundo ziwiri (nthawi zambiri mkati mwa magetsi) pamtundu umodzi wa ndalama, zomwe zimafotokozedwa mwa volts (V). Mpweya, pamodzi ndi pakali pano ndi kutsutsa, amagwiritsidwa ntchito pofotokoza khalidwe la magetsi. Ubalewu ukuwonetsedwa mwa kugwiritsa ntchito Oms malamulo ndi malamulo a dera la Kirchhoff .

Chitsanzo: Galasi la magetsi la United States limagwira ntchito pa 120 V (pa 60 Hz), kutanthauza kuti wina akhoza kugwiritsa ntchito ovomerezeka a 120 V stereo ndi oyankhula awiri. Koma kuti wogwirizanitsa stereo omwewo agwire ntchito bwinobwino ku Australia, yomwe imagwira ntchito pa 240 V (pa 50 Hz), imodzi imafuna mphamvu converter (ndi adap adapter) chifukwa zonse zimasiyanasiyana ndi dziko.
Kukambirana
Maganizo a magetsi, malipiro, zamakono, ndi kukana akhoza kufotokozedwa ndi chidebe cha madzi ndi payipi yomwe ili pansi. Madzi amaimira kuimbidwa (ndi kayendedwe ka electron). Kuthamanga kwa madzi kupyolera mu payipi kukuyimira pakalipano. Kuphatikiza kwa payipi kukuimira kukana; phula losungunuka likhoza kuchepa pang'ono kusiyana ndi payipi lonse. Kuchuluka kwa mavuto omwe amapangidwa kumapeto kwa payipi ndi madzi amaimira mphamvu.
Ngati mukanathira mtsuko umodzi wa madzi mu chidebe pamene mukuphimba mapeto a payipi ndi chala chanu chachikulu, vuto lomwe mumaganizira pa chofufumitsa ndilofanana ndi momwe magetsi amagwirira ntchito. Mphamvu yomwe imatha kusiyana pakati pa mfundo ziwiri - pamwamba pa madzi ndi mapeto a payipi - ndi imodzi yokha ya madzi. Tsopano tiyeni tinene kuti inu mwapeza chidebe chachikulu chokwanira kudzazidwa ndi makilogalamu 450 a madzi (pafupifupi mokwanila kuti mudzaze tebulo la anthu 6). Tangoganizirani mtundu wa chipsinjo chanu chomwe mungachimve pamene mukuyesa kubwezera madzi ambiri. Ndithudi zambiri 'pikani.'
Voltage (chifukwa) ndi chimene chimapangitsa kuti tsopano (zotsatira) zichitike; popanda kuthamanga kulikonse kukakamiza izo, sipadzakhalanso kuyenda kwa magetsi. Kuchuluka kwa ma electron kutuluka ndi magetsi n'kofunika pa ntchito yomwe iyenera kuchitidwa. Ma 1.5B AA mabatire ndiwo zonse zomwe mukufunikira kuti muthe kuyendetsa tepi yochepera. Koma simungaganizire mabatire omwewo kuti athe kugwiritsa ntchito chida chofunikira chofuna 120 V, monga firiji kapena dryer zovala. Ndikofunikira kuganizira za mphamvu zamagetsi ndi zamagetsi, makamaka poyerekeza ziwerengero zotetezedwa pazitetezo .
