Class 12 Physics | Electrostatic Potential & Potential Difference | Electric Potential

In this Class 12 Physics lecture, we will understand Electrostatic Potential & Potential Difference from the basics with clear concepts, formulas, examples and exam-oriented applications. 📚 In this lecture: What is Electric Potential? Why do we consider a unit positive test charge? Formula: V = W/q Meaning and unit of Volt What is Potential Difference? Formula: Vᴮ − Vᴬ = W/q Potential due to a point charge Formula: V = kQ/r Sign of electric potential for positive and negative charges Relation between Electric Field and Electric Potential Numerical problems based on electric potential Common exam mistakes and important points We will focus on WHAT, WHY and HOW, so that you understand the concept instead of simply memorising formulas.
