Coil – Identification, Works or Faults

Mobile phone repairing course ki aaj ke lesson me aap sikh payenge – PCB per Coil ki pahchan kya hai or uske karya-kharabiya etc. ke baare me sikhenge. Mobile cell phone repair me coil ki faults aana aam hai. Coil ki Printed Circuit Board per Pahchan krna bahut hi easy hai. First, aap mobile phone ki ek PCB le.
 

Identification:

Yah mobile cell phone ki motherboard per kuch sections me 2 colours me mil jati hai –

1. Halka Black Colour Ke Sath Dono Side White Stripe

Coil Halka black colour me hoti hai or iske dono taraf ke side me white stripe (dhari) hoti hai. Yah shape or size me different hoti hai. Coil pcb per chhoti-badi hoti hai or kai shapes or sizes ki lagi hoti hai.

2. Blue Colour Ke Sath Dono Side White Dhari

Dusre colour me Coil blue colour ki hoti or iske dono taraf ke side me white stripe hoti hai. Is type ki colour wali coil kuch hi mobile phones ki pcb per lagi hoti hai.

Works: 

Coil ke karya ye hai –
(A) Yah current ko filter krti hai.
(B) Yah current voltage ko decrease (kam) krti hai.


Faults: 

Coil ke faulty hone per isse connected parts ko current or voltage filter nahi hoga.

Practice:

Ab aap apne mobile phone ki PCB per Halke black colour, dono or white dhari wali Coil ki pahchan kijiye.

Kya Aap Jante Hai ?

Mobile Phone Ki PCB Per Coil Ka Karya Hai – Current Voltage Ko Decrease Krna Jabki Boost Coil Current Ko Increase Krne Ka Karya Krti Hai.

Mobile Cell Phone Repairing Course Me Aapne Kya Sikha –
Yadi aap continue mobile re[air sikhe rahe hai to aapne abhi tak 3 small parts –
1. Non Electrolytic Capacitor
2. Electrolytic Capacitor
3. Coil
In 3 parts ki PCB per identification, works or faults ke baare me aapne sikha hai.

Coil – Mobile Repairing FAQs

Q1. Coil kya hota hai mobile me?
Coil ek inductor hota hai jo magnetic field generate karke voltage aur current regulate karta hai. Mobile me power circuits, RF circuits aur backlight circuits me use hota hai.
Q2. Coil fail hone ke symptoms kya hote hain?
Phone boot issue, display backlight fail, charging problem, signal weak hona, ya voltage instability.
Q3. Coil ko kaise test karein?
Multimeter se resistance check karein, inductance measure karein, aur circuit me voltage output observe karein.
Q4. Coil damage hone ke common reasons kya hote hain?
Overvoltage, short circuit, physical damage, soldering fault, ya water damage.
Q5. Coil replace karna safe hai?
Haan, proper soldering aur alignment maintain karein, aur same rating coil use karein.
Q6. Coil jumper se fix ho sakta hai?
Nahi, coil voltage/current regulation aur magnetic field generate karta hai. Jumper se fix nahi hota.
Q7. Coil aur Boost Coil me difference kya hai?
Coil general voltage/current regulation ke liye hota hai, Boost Coil specifically voltage step-up ke liye use hota hai.
