Vim muaj zog, ntsuas hauv watts , yog qhov ua haujlwm ntawm qhov voltage thiab tam sim no, thiab tam sim no yog qhov ua haujlwm ntawm qhov hluav taws xob thiab tsis kam , nws yog ua tau los xam tsis kam los ntawm lub zog thiab qhov hluav taws xob. Ohms txoj cai hais tias voltage = tam sim no x tsis kam , yog li los ntawm rearranging cov mis tsis kam = voltage / tam sim no.

Ib yam li ntawd, puas yog watts tsis kam?

Nws hais tias tam sim no yog sib npaug rau qhov voltage faib los ntawm tus tsis kam los yog kuv = V/R. Qhov no zoo li txo qis tsis kam nyob rau hauv ib qho hluav taws xob system, uas ua rau kom cov dej ntws tam sim no. Lub zog hluav taws xob ntsuas hauv watts.

Ib yam li ntawd, watts ntsuas li cas? Txhawm rau txiav txim siab lub zog , siv ib tug yooj yim multiplication formula. Lub ampere (los yog amps) yog tus nqi hluav taws xob siv. Voltage ntsuas lub zog los yog siab ntawm cov hluav taws xob. Tus naj npawb ntawm watts yog sib npaug rau amps muab faib los ntawm volts.

Yog li ntawd, dab tsi yog qhov kev tiv thaiv ntsuas hauv?

Kev tiv thaiv yog cov ntsuas ntawm nyuaj electrons muaj nyob rau hauv ntws los ntawm ib yam khoom. Nws zoo ib yam li kev sib txhuam ib yam khoom thaum tsiv los yog txav mus los ntawm ib qho chaw. Kev tiv thaiv yog ntsuas hauv ohms; 1 ohm yog sib npaug rau 1 volt ntawm hluav taws xob sib txawv ntawm 1 ampere ntawm tam sim no (1 volt / 1 amp).

Dab tsi yog qhov ua haujlwm ntawm 100 watt 120 volt noob?

Piv txwv li, a 100 watt teeb pom kev zoo ua haujlwm rau 120 volts AC yuav muaj 144 ohms ntawm tsis kam thiab yuav kos 0.833 Amps.
