Ohm txoj cai. Cov kev sib raug zoo ntawm voltage , tam sim no , thiab tsis kam tau piav los ntawm Ohm txoj cai. Qhov kev sib npaug no, i = v / r, qhia peb tias qhov tam sim no , i, ntws los ntawm ib lub voj voog yog ncaj qha proportional rau tus hluav taws xob , v, thiab inversely proportional rau tus tsis kam , r.

Ib yam li ntawd, tib neeg nug, puas muaj kev sib raug zoo ntawm qhov tam sim no thiab qhov hluav taws xob?

Cov qhov yooj yim I-V nkhaus yog qhov ntawd ntawm a resistor, uas raws li Ohm txoj cai ua pov thawj a linear kev sib raug zoo ntawm cov siv hluav taws xob thiab tus qhov tshwm sim hluav taws xob tam sim no ; qhov tam sim no yog proportional rau qhov voltage , yog li tus I-V nkhaus yog txoj kab ncaj nraim tus keeb kwm nrog txoj kab nqes zoo.

Tsis tas li ntawd, kev tiv thaiv cuam tshuam li cas tam sim no? Ohm txoj cai hais tias hluav taws xob tam sim no (I) ntws hauv Circuit Court yog proportional rau qhov voltage (V) thiab inversely proportional rau tus tsis kam (R). Ib yam li ntawd, nce lub tsis kam ntawm Circuit Court yuav txo qis tam sim no ntws yog tias qhov voltage tsis hloov.

Xav txog qhov no, kev sib raug zoo ntawm tam sim no thiab lub zog yog dab tsi?

Hwj chim yog ib qho kev ua haujlwm ntawm qhov hluav taws xob lub sij hawm lub ntim ntawm electrons ( tam sim no ). Hwj chim yog lub peev xwm ua haujlwm thiab ntsuas hauv Watts. Qhov siab dua qhov voltage ntau zog koj muaj nrog tib yam tam sim no (Watts) zog ) = Volts x Amps.

Hloov lub roj teeb qhov hluav taws xob cuam tshuam li cas tam sim no?

me me, tsis zoo them nqi pib txav (electrons). Kev hloov lub roj teeb qhov hluav taws xob cuam tshuam li cas tam sim no ? Qhov siab dua roj teeb voltage , qhov ntau dua qhov ntws ntawm tam sim no hauv Circuit Court.
