Final answer:
The equation for converting from AC to DC voltage is Vdc = Vrms / √2.
Step-by-step explanation:
When converting from AC to DC, the equation for calculating the DC voltage is Vdc = Vrms / √2. The rms voltage (Vrms) is the amplitude of the voltage multiplied by 1/√2. This equation accounts for the fact that AC voltages swing between positive and negative values, while DC voltages are constant.
