Ka dib ku dhawaad 15 sano oo horumarineed, gawaarida tamarta cusub ee tamarta ayaa sameeyay kayd farsamo. Xulashadaiska caabin hore u dallacawaxay go'aamisaa xawaaraha baabuurka wakhtiga ka hor dallacaadda, cabbirka meesha bannaan ee ay ku jirto iska caabbinta hore u dallacaadda, badbaadada korantada sare ee baabuurka, isku halaynta iyo xasilloonida.
Iska caabbinta hore u dallacadu waxay ku dhex jirtaa gaadhiga awooda korantada sare ee capacitor-ka bilowga gaabiskaku dallaca resistor, haddii uusan jirin iska caabin hore u dallaca, dallacaadda hadda aad ayay u weynaan doontaa si aysan u jebin capacitor-ka. Awood-koronto-sare oo si toos ah loogu daray capacitor-ka, oo u dhiganta wareegga-gaaban ee degdegga ah, wareegga-gaaban ee xad-dhaafka ah waxay dhaawici doontaa qaybaha korantada ee sarreeya. Sidaa darteed, marka la naqshadeynayo wareegga, iska caabbinta horay u-qaadista waa in la tixgeliyaa si loo hubiyo badbaadada wareegga.
Waxaa jira laba meelood oo ka mid ah wareegga-voltage sare ee gaariga korontada halkaas oo ahresistor ka horwaxaa la isticmaalaa, kuwaas oo ah kontoroolka mootada ee ka hor inta aan la dallacin iyo wareegga hore ee korantada ee dheeraadka ah. Xakamaynta mootada (wareega rogayaasha) waxa uu leeyahay capacitor weyn, kaas oo u baahan in hore loogu dallaco si loo xakameeyo capacitor-ka ku dallacaaya hadda.
Sida laga soo xigtay xaqiijinta naqshadeynta dhabta ah ee la helay: ceramic resistor waa precharge wax ku ool ah, dheecaan iyo shuruudo kale. Waxay leedahay kuleyl gaar ah oo gaar ah waxayna nuugi kartaa tamar sare inta lagu jiro dallacaadda ka hor waqti gaaban.
