Die essensie van die verskil tussen GS en WS is dat WS gesien kan word as twee stelle afwisselende GS in terme van rigtingveranderinge om 'n effek op die las uit te oefen, wat verstaan kan word as die vektorsom van die twee stelle GS by verskillende tydperke. Vir 'n voldoende kort tydperk kan wisselstroom verstaan word as 'n stel gelykstrome in een rigting.
Wanneer ons elektrisiteit gebruik, sien ons uiteindelik die uitwerking van elektrisiteit. Vir resistiewe ladings is dit 'n termiese effek, so die finale effek van WS en GS is presies dieselfde, beide verhitting, maar aangesien die grootte van die WS gewoonlik verander, kry ons 'n "wgk" om die GS-effek gelyk te stel. Maar vir induktiewe en kapasitiewe ladings het AC 'n rigting en kan glad "deurgaan". Hulle kan nie deur DC bereik word nie. AC kan ook 'n veranderende magnetiese veld produseer, en 'n veranderende magnetiese veld kan 'n veranderende elektriese veld produseer, so die energie kan baie omskakel en maklik oordra. Daarom word wisselstroom meer algemeen gebruik. Byvoorbeeld, 'n transformator kan bloot die waarde van spanning verander, terwyl gelykstroom dit nie direk kan doen nie. Byvoorbeeld, radio-oordrag vereis ook hierdie wisselspannings om 'n veranderende magnetiese veld te genereer, waar in een rigting Sommige gelykstrome nie aan die vereistes kan voldoen nie.
Omdat gelykstroom net een rigting het, is dit relatief eenvoudig om te gebruik. Dit kan maklik in twee toestande verdeel word: hoog en laag. Op hierdie manier kan die fisiese toestand van binêre 0'e en 1'e eenvoudig bereik word. Daarom vereis die chip logika beheer natuurlik gelykstroom, en wisselstroom is te ingewikkeld.
Selfs in sommige kragtoevoerveranderings is dit algemeen om AC eers na DC om te skakel, dan die spanning te stabiliseer en dit te vereenvoudig, en dan 'n ander AC om te keer deur te kap, soos frekwensie-omsetters en omskakeling van kragbronne.
