Rasistan Resistor: Me ke nan?

Muhimmiya Resistor da Yawancin Siffar da Yake?

Muhimmiya resistor ita ce resistor da ake saka a cikin circuit don kula tsakanin karamin. Muhimmiya resistors sun taimakawa kula samun abubuwa da ke sa karamin a cikin circuit. 'Yan gine 'yan gine'yan gine "electric ballast" na iya bayyana wani wurare masu sayen da ake amfani a kan cikin circuit don kula samun dukkanin cikin karamin da voltage. 'Yan gine electric ballast sun zama resistors, capacitors, inductors, ko kuma wasu duka.

Muhimmiya resistors sun iya yawan resistance da karamin. Idan karamin da ke fito a cikin resistor ya fi shi a arewacin balaganin halaye, resistance ya zama. Duk da haka, resistance zai iya rage waɗanda karamin ya rage.

A cikin haka, muhimmiya resistor ta ba da shawarar da karamin da ke fito a cikin circuit.

Muhimmiya resistor shine mutane da load resistor. Saboda haka, yana aiki a cikin system a cikin yadda ake koyar da variable load. Amma a cikin halayen load resistor, resistance take ƙeƙe ƙarin waɗanda karamin da voltage suka ƙeƙe.

Muhimmiya resistors ba su fi yawan amfani a gaba. An juye su da electronic circuits da suke yi aiki mafi yawan amfani.

Muhimmiya Resistor Ta Yi Aiki?

Kalmomin "muhimmiya" na nufin dukkanin. Saboda haka, idan ake magana a cikin muhimmiya resistor, yana nufin cewa muhimmiya resistor tana taimakawa da dukkanin electrical circuit.

Ake amfani da muhimmiya resistor a cikin wurare masu sayen don kula samun changes da kula alama abubuwan da ake amfani a cikin network.

Idan karamin da ke fito a cikin resistor ya fi shi, temperature ya fi shi. Saboda rise da temperature, resistance ya zama.

Saboda haka, increase a resistance ya kula tsakanin karamin da ke fito a cikin network.

Muhimmiya resistors sun fi yawan amfani a cikin automotive applications don bari engine. Idan starter motor ta bari engine, muhimmiya register ta kula tsakanin voltage drain daga battery.

An amfani a cikin lighting applications kamar fluorescent lamp, LED, da neon lights.

Amfani da Muhimmiya Resistor

Muhimmiya resistor tana taimakawa da kula regulate karamin da voltage a cikin electrical system. Tana taimakawa equipment da overcurrent da overvoltage events.

Muhimmiya resistors sun fi yawan amfani a cikin automotive da lighting applications.

Muhimmiya Resistor Don Amfani a Cikin Automotive Applications

A cikin car engine, ake amfani da muhimmiya resistor a cikin ignition system. Kuma ana kiranta da ignition ballast resistor.

Gaskiya, an kara ignition ballast resistor a kan primary source of the ignition coil da coil stud. Tana kula tsakanin riskin failure da ignition coil.

Idan starter motor cranks the engine, the ignition ballast resistor helps to reduce the coil voltage and coil current.

Saboda haka, low current causes a low-temperature rise. And it results in a long life of the ignition coil.

But the ignition system needs a higher voltage which is equal to the voltage of the power source. So, the jumper wire is connected with an ignition ballast resistor. And while starting the engine, the jumper wire provides the required voltage to the ignition coil.

Muhimmiya Resistor a Cikin LED Circuit

LED (Light Emitting Diode) shine wurare masu sayen da ya fi yawan amfani. Zai iya lafiya idan supply voltage ya fi shi a arewacin rated voltage.

Don kula samun hakan, an amfani da muhimmiya resistor don koyar da LED. Tana kula rage voltage across the LED to its rated value.

Za a buƙatar da amfani da appropriate resistance value of ballast resistance. For that consider the below example.

Consider a single LED is connected in series with the supply source. Here, the value of the supply source is higher than the rated voltage. Therefore, you cannot connect directly without a resistor.

Where;

VF = Forward voltage of LED

IF = Forward current of LED
