How do outlets maintain a steady voltage?

Outlets maintain a steady voltage primarily through voltage regulation systems, which include Transformers that step down high voltage from power lines to usable levels. Additionally, the electrical grid employs various technologies, such as voltage stabilizers and automatic voltage regulators, to ensure consistent voltage levels despite fluctuations in demand. Circuit breakers and fuses also protect the system from overloads, helping to maintain a stable voltage supply. Lastly, capacitors may be used to smooth out voltage variations and enhance stability.
