RMS Voltage, or Root Mean Square Voltage, is a measure of the effective value of an alternating current (AC) voltage, representing the equivalent direct current (DC) value that would deliver the same power to a load. It is particularly useful for comparing AC and DC systems and is calculated by taking the square root of the average of the squares of all instantaneous values over one cycle.

Direct current (DC) is a type of electrical current that flows consistently in one direction, making it ideal for applications where a stable voltage is required, such as in batteries and electronic devices. Unlike alternating current (AC), DC is characterized by a constant voltage level, which makes it crucial for low-voltage or portable power systems.
