Daim ntawv thov. Voltage dividers yog siv los kho cov theem ntawm lub teeb liab, rau kev tsis ncaj ncees ntawm cov khoom siv hauv amplifiers, thiab ntsuas qhov voltages. Ib tug Wheatstone choj thiab ib tug multimeter ob leeg muaj xws li voltage dividers. Lub potentiometer yog siv los ua qhov sib txawv ntawm qhov sib txawv ntawm qhov kev tswj lub ntim ntawm ntau lub xov tooj cua.
Puas voltage faib ua haujlwm tau zoo?
Lawv tsuas yog txo qhov tso zis hluav taws xob, rau txhua qhov muab tam sim no. Lub zog sib txawv yog nkim li cua sov. Yog hais tias koj muaj 10V nyob rau hauv, thiab 5V tawm, ces lawv yog 50% npaum. Lawv muaj lawv cov txiaj ntsig, txawm li cas los xij!
Puas voltage divider txo tam sim no?
Voltage Tapping Points in a Divider Network
Tus nqi tiv thaiv no yuav txwv qhov kev khiav ntawm tam sim no los ntawm Circuit Court uas tsim los ntawm cov khoom siv hluav taws xob, VS.
Koj siv lub tshuab hluav taws xob li cas?
Voltage Divider Formula / Equation
Kev sib npaug kom pom qhov tso zis voltage ntawm Divider Circuit: R2 / R1 + R2=Ratio txiav txim siab qhov ntsuas qhov ntsuas ntawm qhov ntsuas hluav taws xob.
Vim li cas nws thiaj hu ua hluav taws xob faib hluav taws xob?
Cov zis hluav taws xob sib npaug ntawm cov khoom siv hluav taws xob ntsuas los ntawm qhov piv ntawm cov resistors: hauv qab resistor muab faib los ntawm cov lej ntawm cov resistors. Qhov piv ntawm cov resistors ib txwm tsawg dua 1 rau ib qho txiaj ntsig ntawm R1start ntawv, R, 1, ntawv kawg thiab R2start ntawv, R, 2, ntawv kawg. … Qhov no yog qhov uas Circuit Court tau txais nws lub npe menyuam yaus: voltage divider.
