An samun inductance da kuma an samun resistance suna biyu na kayayyakin kayayyakin, wadanda suka nuna yanayin ideal na kawai inductance ko kawai resistance a cikin kayayyaki. A nan bayanen biyu na kayayyakin da kuma mafi yawan musamman:
An Samun Kayayyakin Da Resistor
Takaitaccen
An samun kayayyakin da resistor shi ne kayayyaki mai kawai rukunin resistance (R) karkashin wata daga wurare (kamar inductors L ko kuma capacitors C). Rukunin resistance suna amfani a cikin kayayyaki don nuna yanayin da ake kasa energy, kamar tasirin tsafta.
Mafi Yawan Musamman
Voltage da kuma current a fagen: A cikin an samun kayayyakin da resistor, voltage da kuma current suna a fagen, yana nufin cewa faruwar da ake kawo bayan daga baya ita ce 0°.
Ohm's Law: Inganci game da voltage (V) da kuma current (I) ta ci gaba kan Ohm's law, yana nufin V=I×R, inda R shine resistance ta resistor.
Kasuwanci power: Rukunin resistance ya kasance electrical energy kuma ya zama heat energy, ya kasance ta hanyar power P=V×I ko kuma P= V2/R ko kuma P=I 2×R.
Amfani
Heating element: Rukunin resistance yana da muhimmanci a cikin abubuwa masu heating, kamar electric water heater, electric iron, k.s.a.
Current limiting element: An amfani a cikin kayayyaki don kawo karfi ga current don ba a yi lalace a wurare.
Voltage divider: A cikin voltage divider circuit, an amfani da resistor don koyar voltage daidai.
An Samun Inductor Circuit
Takaitaccen
An samun inductive circuit shi ne kayayyaki mai kawai inductive elements (L) karkashin wata daga wurare. Inductor yana nuna yanayin da ake kasa magnetic field energy kuma yana da kyau a cikin coils mai windi.
Mafi Yawan Musamman
Voltage lead current 90° : A cikin an samun inductive circuit, voltage yana 90° ahead of the current (ko +90° phase difference).
Inductive reactance: Blocking effect ta inductive element ga alternating current yana nufin inductive reactance (XL), da yake da kalmomin frequency, formula ta ce
XL=2πfL, inda f shine frequency ta alternating current da kuma L shine inductance value ta inductor.
Reactive power: Inductive elements ba su kasance energy, amma za su kasa energy a magnetic field kuma za su shirya a cycle na uku, saboda haka akwai reactive power (Q) a cikin inductive circuit, amma ba da kasuwanci energy.
Amfani
Filters: Inductors suna amfani a cikin filters, hasken low-pass filters, don kawo karfi ga high-frequency signals.
Ballast: A cikin fluorescent lamp circuits, an amfani da inductors don kawo karfi ga current da kuma bayar starting voltage da ya dace.
Resonant circuit: Idan an amfani da capacitive components, inductors zai iya form LC oscillating circuits don bayar oscillating signals na frequency na da take.
Bayanen
An samun resistance circuit: yanayin voltage da kuma current a fagen, ci gaba kan Ohm's law, energy kasance a resistance, zama heat.
An samun inductive circuit: yanayin voltage leading current 90°, inductive reactance, energy kasa a magnetic field da kuma shirya a cycle na uku, ba da kasuwanci energy.
A cikin amfani, an samun resistance ko inductance circuits ba su fitowa, amma yawanci an samun wurare da suka fiye a cikin kayayyaki, amma fahimtar biyu na kayayyakin da ya bayar taimakawa wajen analize da kuma design kayayyaki masu yawan wurare.
