Which AC voltage value will produce the same amount of heat as a DC voltage, when applied to the same resistance?

RMS stands for Root Mean Square, which is a mathematical calculation used to determine the effective value of a varying alternating current (AC) voltage. For any AC waveform, the RMS value is exactly equivalent to the direct current (DC) voltage that would produce the same heating effect across a given resistance. Other measurements like peak, peak-to-peak, or average do not directly equate to DC power dissipation. Peak measures the maximum amplitude, while the average voltage for a full sine wave is zero. RMS is the universal standard for comparing AC power output to DC power output.
