📖 Electric Potential and Capacitor - Detailed Notes

🔥 Electric Potential - Introduction

🔹 Electric Potential ek scalar quantity hai jo kisi unit charge ko ek point
tak le jaane ke liye required work ko represent karta hai.
🔹 Agar electric field (E) me ek charge q rakha jaye, toh uska potential
energy ka formula hai:

👉U=q×V

🔹 Electric Potential ka basic formula hai:

👉V=U/q

Matlab potential energy (U) ko charge (q) se divide karne par electric potential
milta hai.

⚡ Potential due to a Point Charge

Agar ek charge Q kisi point P pe potential create karta hai, toh formula hoga:

👉 V = (K × Q) / r

Jahan,
✅ K = Coulomb's Constant (9 × 10⁹ Nm²/C²)
✅ r = Distance from charge

⚡ Potential Energy between Two Charges

Agar do charges Q₁ aur Q₂ ke beech electric potential energy find karni ho,
toh formula hoga:

👉 U = (K × Q₁ × Q₂) / r

✅ Ye formula electrostatic force ke kaam ko represent karta hai!

⚡ Relation between Electric Field and Potential

Electric field aur potential ka relation diya jata hai:

👉 E = - (dV / dx)

✅ Agar electric field uniform ho, toh:
