Long ol 120V sistem, dispela i min olsem i no moa long 3.6V drop long ol wanwan seket na 6V olgeta. Ol 'sensitive electronics' i nidim strongpela mak bilong 1.5-2.5%.

Voltej drop i go antap stret wantaim longpela bilong kondukta. Taim yu daunim longpela bilong waia, dispela i save daunim voltej aninit long wankain lod bilong karent. Dispela proporsenel rilesensip i min olsem ol longpela kebol ran i nidim bikpela waia gej long holim gutpela voltej drop level.

Sapos 'voltage drop' tumas i no save kamapim bagarap hariap tasol em i save mekim 'wear' i go hariap long planti rot. Ol mota i save hat tumas bikos ol i save kisim bikpela pawa, ol ilektronik divais i save kisim hevi long ol voltej we i no stret, na ol bateri i save kisim hevi long sasim. Sapos yu wok gut wantaim bikpela 'voltage drop' dispela i save sotim laipspan bilong ol ikwipmen tru.

Long ol DC seket, yusim: Voltage Drop=Current × Resistance. Painim 'conductor resistance' long ol tebol bilong 'wire gauge' (ohms long 1,000 fit), multiplaim long trupela longpela, na multiplaim wantaim 'load current'. Ol kalkuleta long intanet i mekim dispela wok i kamap isi long tupela AC na DC seket long rot bilong lukautim ol spesifikesen bilong waia otomatik.

Voltage drop em i taim we voltage i go daun bikos long 'conductor resistance' taim pawa i ron long ol lektrikel seket

Ol bikpela samting we i save mekim 'voltage drop' em longpela bilong 'conductor', 'wire gauge', kain samting, na bikpela bilong 'load current'

Ol standet rekomendesen i limitim voltej drop i go long 3-5% bilong sos voltej, tasol ol sensitif ikwipmen i nidim strongpela mak
