[′swämp·iŋ ri zis·tər] (electronics) Resistor muab tso rau hauv cov emitter lead ntawm transistor circuit kom txo qhov kub ntawm qhov kub ntawmemitter-base junction resistance.
Dab tsi yog swamping resistance thiab nws txuas li cas?
Tus swamping kuj yog txuas nrog cov kauj raws li qhia hauv daim duab. Txij li thaum qhov kev tiv thaiv ntawm kev txav coil tsim ib feem me me ntawm kev sib xyaw ua ke, qhov kev faib ua feem ntawm cov dej ntws sib faib nruab nrab ntawm lub 'meter' thiab shunt yuav tsis hloov nrog qhov kev hloov ntawm qhov kub thiab txias.
Dab tsi yog swamping resistance hauv Pmmc?
Qhov yooj yim kub them nqi hluav taws xob rau PMMC siv qhov kev tiv thaiv hauv cov kab nrog lub kauj txav, raws li qhia hauv daim duab. Lub resistor hu ua swamping resistor. Nws yog tsim los ntawm manganin uas xyaum xoom kub coefficients, ua ke nrog tooj liab hauv qhov piv ntawm 20/1 lossis 30/1.
Dab tsi yog swamping resistance ua los ntawm?
Swamping resistor yog ib qho alloy ntawm manganin thiab tooj liab hauv qhov piv ntawm 20: 1.
Yuav ua li cas cov swamping kuj stabilizes qhov biasing?
Swamping resistor yog cov lus tawm tswv yim tsis zoo siv nyob rau hauv swamped amplifier kom stabile qhov nce voltage. Txhawm rau kom ruaj khov qhov nce voltage, emitter tsis kam yog unbypassed, ua ac emitter tawm tswv yim. Lub emitter tam sim no ntws txawm tias qhov tsis muaj kev cuam tshuam emitter tsis kam thiab ac voltage tshwm hla.
