UP Board Class 12 Physics – Electrostatic Potential and Capacitance
“Electrostatic Potential and Capacitance” is an important chapter of UP Board Class 12 Physics that explains how work is done in moving a charge within an electric field. Students learn the concept of electric potential, potential difference, and electric potential energy, which are essential for understanding electric circuits.
The chapter describes the relation between electric field and potential, enabling students to visualise how electric forces influence energy. A key portion focuses on equipotential surfaces, their properties, and applications. The chapter also introduces electrostatic capacitors, devices used to store electric charge and energy. Students explore different types of capacitors, especially parallel plate capacitors, and study how factors like plate area, distance, and dielectric material affect capacitance.
The concept of energy stored in a capacitor and the role of dielectrics help students understand real-life uses in electronics, power systems, and communication devices. Numerical problems, derivations, and graphs strengthen analytical skills and prepare students for board exams and competitive tests.
