Misalai da Komponento mai Kudin (Active) da Komponento mai Tafi (Passive)?

Komponento mai kudin da komponento mai tafi suna cikin abubuwa uku na ayyukan elektronika. Komponento mai kudin yana bayar hankali zuwa kudin elektronika, kuma haka ya samu kyakkyawan bayar hankali zuwa hukumomin hanyoyin hankali. Komponento mai tafi zai iya tabbatar hankali ne, kuma zai iya tabbatar ko gafara shi.

Ayyuka da Duk Komponento na Elektronika

Ayyukan elektronika da suka jin kudin suna haɗa da conductor don samun kudin mai sauƙi. Idan wasu mahaɗa masu haɗa su ideal conductor (yani ba su da resistance), kuma duk babin kudin zai iya haɓaka a matsayin abubuwan uku na kan abubuwa da suke bayar hankali ko gafara hankali daga kudin:

• Komponento mai kudin

• Komponento mai tafi

Electrical symbols ana amfani da su don tasirar komponento mai kudin da komponento mai tafi. Misalai na kudin mai sauƙi na biyu an samun ayyukan elektronika ta fi sani:

Komponento Mai Kudin

Wani komponento mai kudin shine komponento na elektronika wanda ke bayar hankali zuwa kudin. Komponento mai kudin suna da kyakkyawan bayar hankali zuwa hanyoyin hankali (yani hanyoyin bayar hankali). Duk kudin elektronika zai iya ɗaukar waɗanda komponento mai kudin.

Misalai na biyu na komponento mai kudin sun hada da:

• Voltage sources

• Current sources (e.g. DC current source)

• Generators (such as alternators and DC generators)

• All different types of transistors (such as bipolar junction transistors, MOSFETS, FETs, and JFET)

• Diodes (such as Zener diodes, photodiodes, Schottky diodes, and LEDs)

Voltage Sources

A voltage source is an example of an active component in a circuit. When current leaves from the positive terminal of the voltage source, energy is being supplied to the circuit. As per the definition of an active element, a battery can also be considered as an active element, as it continuously delivers energy to the circuit during discharging.

Current Sources

A current source is also considered an active component. The current supplied to the circuit by an ideal current source is independent of circuit voltage. As a current source is controlling the flow of charge in a circuit, it is classified as an active element.

Transistors

Although not as obvious as a current or voltage source – transistors are also an active circuit component. This is because transistors are able to amplify the power of a signal (see our article on transistors as an amplifier if you want to know exactly how).

As this amplification is essentially controlling the flow of charge – transistors are hence classified as an active component.
