txhawm rau nrhiav lub hauv paus txhais tau tias square ntawm ib pawg ntawm cov lej, square tag nrho cov lej hauv cov teeb thiab tom qab ntawd nrhiav cov lej lej ntawm cov squares. Siv lub hauv paus square ntawm qhov tshwm sim. Qhov no yog lub hauv paus txhais tau tias square.
Tus nqi rms xam li cas?
RMS Voltage Equation
Tom qab ntawd RMS voltage (VRMS) ntawm sinusoidal waveform yog txiav txim los ntawm muab qhov siab tshaj qhov hluav taws xob los ntawm 0.7071, uas yog tib yam li ib qho faib los ntawm lub hauv paus square ntawm ob (1/√2).
RMS tus nqi yog dab tsi?
RMS tus nqi yog tus nqi zoo ntawm qhov sib txawv ntawm qhov sib txawv lossis tam sim no Nws yog qhov sib npaug DC (tsis tu ncua) tus nqi uas muab cov txiaj ntsig zoo ib yam. Piv txwv li, lub teeb txuas nrog 6V RMS AC cov khoom siv yuav ci nrog tib lub teeb ci thaum txuas nrog 6V DC cov khoom ruaj khov.
Yog RMS AC lossis DC?
RMS txhais tau tias yog AC sib npaugqhov hluav taws xob uas ua rau tib yam ntawm cov cua sov lossis lub zog hauv ib qho hluav taws xob yog tias tib yam dhau los ntawm DC voltage rau tus resistor.
Is 220v RMS lossis peak?
Peb paub tias qhov ntsuas hluav taws xob yog qhov feem ntau rms tseem hu ua lub hauv paus txhais tau tias square tus nqi ntawm qhov voltage. Yog li peb tuaj yeem hais tias qhov hluav taws xob siab tshaj plaws hauv 220 V, 50 Hz Ac qhov chaw yog 311 V.
