This lecture covers the calculation of the electric field created by different charge arrangements, starting with a point charge. The instructor explains the relationship between electric flux density, electric field, and electric potential. By considering a charged sphere, the lecture demonstrates how to calculate the electric field and electric potential at a given point. The concept of equipotential surfaces and their significance in determining the electric field direction is discussed. The lecture also delves into the calculation of electric potential using integrals and the choice of reference point. It concludes by highlighting the limitations of the formulas for point charges and the need for more complex theories in quantum electromagnetics.
