परिचय
Aapne school ke lab ya electrical board pe dekha hoga — “Danger: 220V” ya “Battery: 9V”. Lekin yeh V (Volt) hota kya hai?
Agar aap electronics seekh rahe ho ya basics samajhna chahte ho, toh Voltage ek aisa core concept hai jo har beginner ko clearly samajhna chahiye.
Is blog mein hum easy explanation ke saath dekhenge:
- Voltage kya hota hai?
- Kaise kaam karta hai?
- Aur iska real-life use kya hai?
🔍 What is Voltage? | Voltage kya hota hai?
✅ Definition:
Voltage = Electrical Pressure
Yeh potential difference hota hai jo electrons ko circuit mein flow karne ke liye force karta hai.
Hindi mein: Voltage ek tarah ka दबाव (pressure) hai jo electrons ko एक जगह से दूसरी जगह तक भेजता hai.
जैसे पानी में pressure se flow hota hai, वैसे ही voltage electrons ko wire ke through flow karata hai.
📐 Voltage ka Unit:
| Property | Value |
| SI Unit | Volt (V) |
| Symbol | V |
| Measured by | Voltmeter |
🧮 Formula:
Voltage (V) = Work Done (W) / Charge (Q)
Agar aap kisi charge ko move karne ke liye energy use karte ho, toh usse hi voltage define hota hai.
⚙️ Why is Voltage Important?
Voltage ke bina current flow nahi karta. Aur bina current ke electronics kaam nahi karte.
🔌 Real-World Impact:
- Bulb glow nahi karega 💡
- Fan nahi chalega 🌀
- Battery charge nahi hogi 🔋
- Mobile, TV, Laptop sab dead ho jaayenge 📱🖥️
⚠️ Har Device ka Voltage Limit hota hai:
| Device | Working Voltage |
| Mobile Battery | 3.7V |
| AA Battery | 1.5V |
| Home Supply | 22V – 240V |
⚠️ Agar voltage limit cross ho jaye, toh device burn ya damage ho sakta hai!
🧪 Real-Life Example:
Example 1:
Aapne ek 9V battery li, usse LED se connect kiya.
Battery electrons ko push karti hai, aur LED glow karta hai. That’s voltage in action.
Example 2:
Ghar ki bijli 220V hoti hai.
Yeh voltage appliances (TV, fridge, fan) ko energy provide karta hai.
Voltage Zyada ya Kam Hone Par:
- Fan slow/fast chalta hai
- Light dim ya zyada bright hoti hai
- TV, charger damage ho sakta hai
✅ Conclusion:
Voltage ek essential concept hai jo har electronics beginner ko samajhna chahiye.
Yeh current ke flow ka reason hai, aur bina iske circuit dead hai.
Jab bhi aap koi device use karein ya circuit design karein, voltage rating check karna बहुत जरूरी है!
