A passive component is a module that does not require energy to operate, except for the available alternating current (AC) circuit that it is connected to. A passive module is not capable of power gain and is not a source of energy. A typical passive component would include resistors, inductors, capacitors and transformers, which together are required to build any electrical or electronic circuit.
Passive devices can be used individually or connected together within a circuit, either in a series or in a parallel combination to control complex circuits or signals.
Types of Passive Components
A capacitor is a passive component that can gather and hold a charge in a way that is similar to how a battery functions. This type of passive component is made of 2 close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to a power source. One plate accumulates a positive charge and the other plate accumulates a negative charge. It can hold the charge even when the voltage is no longer applied. Different types of capacitors are film capacitors, mica capacitors, ceramic capacitors, electrolytic capacitors, aluminium electrolytic capacitors, tantalum electrolytic capacitors and power factor correction capacitors.
Another type of passive component is the resistor. A Resistor is an electrical device that resists the flow of electrical current. Although a resistor does not amplify or shape the electric current in any way, it's a powerful little device as it enables you to put the brakes on current flow in a very controlled way.
An inductor is a passive component that can store or deliver energy but cannot generate it. An ideal inductor is lossless, meaning that it can store energy indefinitely as no energy is lost as heat. Inductors are sometimes known as coils, chokes, electromagnets and solenoids.
A ferrite core is a ceramic compound that includes a mix of iron and another type of metal. Ferrite is common in many types of electrical components, including antennas. This magnetic core features wound components; some examples would include windings from a transformer and inductors. It is useful because of its low electrical conductivity and high magnetic permeability.

Passive sehemu ni moduli ambayo haihitaji nishati ya kufanya kazi, isipokuwa kwa ajili ya inapatikana mzunguko wa sasa (AC) kwamba ni kushikamana na. Moduli passive si uwezo wa nguvu faida na si chanzo cha nishati. Vipengele vya kawaida vya passiv ni pamoja na resistors, inductors, capacitors na transformers, ambayo pamoja zinahitajika kujenga mzunguko wowote wa umeme au elektroniki. Vifaa vya Passive vinaweza kutumika kwa mtu binafsi au kuunganishwa pamoja ndani ya mzunguko, ama katika mfululizo au katika mchanganyiko sambamba kudhibiti mizunguko tata au ishara. Kondensator ni sehemu ya passively ambayo inaweza kukusanya na kushikilia malipo katika njia ambayo ni sawa na jinsi betri kazi. Aina hii ya sehemu ya pasifu ni alifanya ya conductors mbili karibu (kwa kawaida sahani) ambayo ni kutengwa na dielectric nyenzo. Vipande hivyo huchanganya umeme vinaposhikamana na chanzo cha umeme. Sahani moja hukusanya malipo mazuri na sahani nyingine hukusanya malipo mabaya. Inaweza kushikilia malipo hata wakati voltage si tena kutumika. Aina tofauti za capacitors ni capacitors filamu, mica capacitors, ceramic capacitors, electrolytic capacitors, alumini electrolytic capacitors, tantalum electrolytic capacitors na nguvu sababu marekebisho capacitors. Aina nyingine ya sehemu passive ni upinzani. Resistor ni kifaa cha umeme ambacho hupinga mtiririko wa umeme. Ingawa resistor haizidishi au kuunda umeme kwa njia yoyote, ni kifaa kidogo chenye nguvu kwani kinakuwezesha kuweka breki kwenye mtiririko wa sasa kwa njia iliyodhibitiwa sana. Inductor ni sehemu passive ambayo inaweza kuhifadhi au kutoa nishati lakini haiwezi kuzalisha. Inductor bora ni lossless, maana kwamba inaweza kuhifadhi nishati kwa muda usiojulikana kama hakuna nishati ni kupotea kama joto. Inductors ni wakati mwingine inajulikana kama coils, chokes, electromagnets na solenoids. Msingi wa feriti ni mchanganyiko wa kauri unaojumuisha mchanganyiko wa chuma na aina nyingine ya chuma. Ferrite ni ya kawaida katika aina nyingi za vipengele vya umeme, ikiwa ni pamoja na antena. Hii magnetic msingi makala jeraha vipengele; baadhi ya mifano ni pamoja na windings kutoka transformer na inductors. Ni muhimu kwa sababu ya conductivity yake ya chini ya umeme na high magnetic permeability. Vifaa vya ulinzi Vifaa vya ulinzi vya kuzidisha nguvu ni sehemu ya karibu kila nyumba na ofisi leo. Vifaa hivyo vya umeme vinaweza kuokoa vifaa vyako vya umeme na kuimarisha maisha ya umeme. RS ni muuzaji wa vifaa vya passively na aina mbalimbali ya bidhaa ya ubora kutoka wazalishaji kuongoza duniani kote.
