Kumvetsetsa malamulo amenewa ndikofunika kwambiri kwa aliyense woyendetsa dera, magetsi, kapena magetsi.
Malamulo Oyambira Oyendayenda
Malamulo oyendetsa magetsi amayang'ana mbali zing'onozing'ono zoyendetsa magawo, magetsi, zamakono, mphamvu, ndi kukana, ndikufotokozera momwe zimagwirizanirana. Mosiyana ndi maubwenzi ovuta kwambiri ndi magetsi, zofunikira izi zimagwiritsidwa ntchito nthawi zonse, osati tsiku ndi tsiku, chifukwa cha wina aliyense amene amagwira ntchito ndi zamagetsi. Malamulo amenewa adapezeka ndi Georg Ohm ndi Gustav Kirchhoff ndipo amadziwika kuti Ohms lamulo ndi malamulo a Kirchhoff.
Oms Law
Lamulo la oms ndilo mgwirizano pakati pa ma voltage, zamakono ndi kutsutsana m'madera ndipo ndi njira yodziwika bwino (komanso yophweka) yomwe imagwiritsidwa ntchito pa zamagetsi. Oms law amanena kuti pakalipano kupitilira kukana ndikofanana ndi mpweya wotsutsana ndi kukana (I = V / R). Oms lawingalembedwe m'njira zosiyanasiyana, zomwe zimagwiritsidwa ntchito nthawi zambiri. Mwachitsanzo - Voltage ndi yofanana ndi yomwe ikuyenda nthawi yomwe imatsutsa (V = IR) ndipo kukana kuli kofanana ndi mpweya womwe umagawanika womwe umagawidwa (R = V / R). Lamulo la oms ndi lothandizira pakuzindikira kuchuluka kwa mphamvu zomwe dera likugwiritsa ntchito kuyambira pamene mphamvu ya dera ikuyenda mofanana ndi yomwe ikuyenda nthawi yomwe magetsi (P = IV). Lamulo la oms lingagwiritsidwe ntchito kuti lizindikire mphamvu ya dera lokha malinga ndi zigawo ziwiri mu malamulo a ohms omwe amadziwika ndi dera.
The Ohms malamulo malamulo ndi chida champhamvu kwambiri pa zamagetsi, makamaka popeza maulendo akuluakulu angakhale osavuta, koma ohms malamulo ndi ofunikira pamagulu onse oyendetsa magetsi komanso zamagetsi. Chimodzi mwa zofunikira kwambiri za malamulo a Ohms ndi mgwirizano wa mphamvu ndi kudziwa momwe mphamvu zimatayira ngati kutentha kwa gawo. Kudziwa izi ndizofunikira kwambiri kuti chigawo choyenera ndi mphamvu yoyenera ikusankhidwa kuti mugwiritse ntchito. Mwachitsanzo, posankha 50 ohm pamwamba mount resistor yomwe idzawona 5 volt pa nthawi yoyenera kugwira ntchito, podziwa kuti iyenera kutaya (P = IV => P = (V / R) * V => P = (5volts ^ 2) / 50ohms) =. Watts 5) ½ Watt pamene akuwona 5 volts amatanthauza kuti kukana ndi mphamvu yaikulu kwambiri kuposa ma watts a 0.5 ayenera kugwiritsidwa ntchito. Kudziwa kugwiritsa ntchito mphamvu kwa zigawozi mu dongosolo kumakuthandizani kudziwa ngati zina zotentha kapena zozizira zingakhale zofunikira ndikulamula kukula kwa mphamvu ya dongosolo.
Kirchhoff & # 39; s Circuit Laws
Malamulo a Tying Ohms pamodzi ndi malamulo a dera la Kirchhoff. Malamulo Amtundu wa Kirchhoff akutsatira ndondomeko yosungiramo mphamvu ndipo amati chiwerengero chonse cha zonse zomwe zikuyenda pakadutsa (kapena mfundo) pa dera ndilofanana ndi chiwerengero cha zomwe zikuchitika panopa. Chitsanzo chophweka cha Malamulo Amakono a Kirchhoff ndi magetsi ndi dera loperewera ndi magawo angapo otsutsana. Chimodzi mwa zigawo za dera ndi kumene magetsi onse amagwirizana ndi magetsi. Pachifukwa ichi, magetsi akupereka pakali pano ndipo mfundo yomwe ikuperekedwayo imagawidwa pakati pa zotsutsana ndipo imatuluka kuchokera ku node yomweyi komanso mpaka kumatsutso.
Kirchhoff's Voltage Law imatsatiranso mfundo yosungira mphamvu ndipo imanena kuti chiwerengero cha migwirizano yonse m'dera lonse chiyenera kukhala chofanana. Kuwonjezera chitsanzo choyambirira cha magetsi okhala ndi magulu angapo omwe ali ofanana pakati pa magetsi ndi nthaka, mbali iliyonse yamagetsi, kukana, ndi nthaka zimawona mphamvu yomweyo pamtunda chifukwa chakuti pali chinthu chimodzi chokha chokhazikika. Ngati mzerewu uli ndi magawo otsutsana nawo mndandanda wa magetsi pamtunda uliwonse udzagawidwa molingana ndi oms law.
