📚 Topic Summary
Electric field superposition is the principle that the total electric field at a point due to multiple charges is the vector sum of the electric fields created by each individual charge at that point. In simpler terms, to find the total electric field, you calculate the electric field due to each charge separately and then add them together as vectors, considering both magnitude and direction. This principle is fundamental to understanding how multiple charges interact and influence the electric field around them.
