Electric Fields: Charge Distributions (I)

This lecture covers the calculation of electric fields from continuous charge distributions, including single charges, line charges, 2D planes of charges, and charged 3D bodies. The superposition principle is introduced, allowing for the summation of field contributions from individual charges. Various integration techniques are discussed for 1D, 2D, and 3D charge distributions. The lecture emphasizes the importance of analyzing the distribution and symmetry of the problem before calculation. Strategies for simplifying calculations through symmetry considerations are presented, along with the concept of charge densities in 1D, 2D, and 3D. The lecture concludes with the calculation of the electric field from a continuous charge distribution on an infinitely long line.
