 🧾 Introduction: Electronics world mein diode ek basic aur important component hai. Ye ek aisa device hai jo current ko sirf ek direction me flow karne deta hai. Is blog me hum samjhenge diode kya hota hai, kaise kaam karta hai, uske types aur use. --- 🔹 1. Diode Kya Hota Hai? Diode ek semiconductor device hai jo electric current ko sirf forward direction me flow karne deta hai aur reverse direction me rokta hai. ⚙ Structure: Diode do part se milke banta hai: P-type aur N-type material. Dono ke junction ko PN-junction kehte hain. ➕ Forward Bias: Jab positive terminal P-side se judta hai aur negative terminal N-side se – tab diode current pass karta hai. ➖ Reverse Bias: Agar polarity ulti ho jaaye to diode current block kar deta hai. --- 🔹 2. Diode Ke Prakar (Types of Diode): 🧩 A. PN Junction Diode Sabse basic diode Current sirf forward bias me flow karta hai Use: Rectifier circuits 🧩 B. Zener Diode Specially reverse bias me kaam karta hai Voltage regulator circuits me use hota...

  📘 Introduction: Pichle blog me humne samjha capacitor kya hota hai aur kuch basic types dekhe the. Is blog me hum aur details me Fixed aur Variable Capacitors ke baare me padhenge. Har ek type ka kaam, use aur example diya gaya hai. --- 🔹 1. Fixed Capacitors: Inka capacitance ek fixed value hota hai. Ye sabse common type ke capacitors hote hain electronics circuits me. 🧩 A. Ceramic Capacitor Shape: Chhoti gol plate jaisi Range: pF se µF tak Use: High frequency circuits, RF circuits Note: Non-polarized hote hain --- 🧩 B. Electrolytic Capacitor Shape: Cylinder jaisa Range: µF to mF Use: Power supply filtering Note: Polarized hota hai, sahi polarity me lagana hota hai --- 🧩 C.

Film Capacitor Stable aur long life Use: High current circuits Shape: Rectangular box type --- 🔹 2. Variable Capacitor: Inka capacitance badal sakta hai. Manual ya automatic tuning ke...

 1. Capacitor Kya Hota Hai? Capacitor ek aisa electronic component hai jo electric charge store karta hai. Iska kaam ek chhoti si battery ki tarah hota hai — lekin temporary storage ke liye. --- 2. Capacitor Ka Kaam: 🔋 Charge Store Karna: Capacitor do conductive plates aur ek insulator (dielectric) se bana hota hai. Jab voltage lagaya jaata hai, ye plates charge store kar leti hain. ⚡ Instant Energy Supply: Jab zarurat padti hai, capacitor turant stored energy ko circuit me release karta hai. Isliye isse backup power ke liye bhi use kiya jaata hai. 📉 Voltage Smooth Karna: Capacitor signal ya voltage me aane wale fluctuations ko smooth karne ka kaam karta hai — jaise fan ka speed stable rakhna. --- 3. Capacitor Kaha Use Hote Hai? Power Supply Circuits – Voltage ko filter karne ke liye Mobile Phones – Sudden power requirement ke liye Fan Regulators – Speed control karne ke liye Inverters & UPS – Backup ke time power supply dene ke liye --- 4. Capacitor Ka Symbol: --- 5. Capacit...

 ## Resistor Kya Hota Hai? Resistor ek aisa electronic component hai jo **current ke flow ko control karta hai**. Iska kaam hota hai circuit me resistance create karna. --- ## Resistor Ka Main Kaam: 1. **Current Ko Limit Karna**    - Resistor se current ki value control hoti hai. 2. **Voltage Drop Create Karna**    - Circuit me alag-alag jagah pe voltage divide karne ke kaam aata hai. 3. **Heat Produce Karna**    - Power resistors heat banate hain, use fans ya heaters me use kiya jaata hai. --- ## Resistor Ka Symbol: Electrical circuit me resistor ka symbol ek zig-zag line hoti hai:__/\/\/\__ --- ## Resistor Ki Unit: - **Ohm (Ω)** hoti hai. - Jaise: 1kΩ = 1000 Ohms --- ## Resistor Color Code: Resistor ke upar color bands hote hain jo uski value batate hain. Jaise: - Brown, Black, Red = 1kΩ --- ## Video: Resistor Kya Hota Hai?
