The superposition principle says that when multiple charges create electric fields in the same space, the total field at any point is simply the vector sum of the individual fields each charge would create alone. The key insight is that electric fields don't interfere with or weaken each other—they add independently, so you can solve complex multi-charge problems by finding each field separately, then combining them as vectors.
