Effective Voltage Calculator


About Effective Voltage Calculator (Formula)

The Effective Voltage Calculator is a tool used to calculate the effective voltage in an AC (alternating current) circuit. This calculator helps determine the equivalent voltage that produces the same amount of power as a corresponding DC (direct current) circuit.

The formula for calculating the effective voltage depends on the type of waveform being considered. For a sinusoidal waveform, such as the commonly used AC waveform, the formula to calculate the effective voltage, also known as the root mean square (RMS) voltage, is:

Vrms = Vpeak / √2

Where: Vrms = Effective voltage or RMS voltage Vpeak = Peak voltage of the sinusoidal waveform

To use this formula, you need to know the peak voltage of the sinusoidal waveform. Divide the peak voltage by the square root of 2 (√2) to obtain the effective voltage.

It’s important to note that the effective voltage represents the equivalent DC voltage that would produce the same power as the AC waveform. It is widely used to compare AC and DC circuits and determine the heating, lighting, or other power-related aspects in an AC system.

When using the Effective Voltage Calculator, ensure accurate measurement or knowledge of the peak voltage of the AC waveform to obtain reliable results. Additionally, consider any specific adjustments or considerations needed for different waveform shapes or complex AC circuits.

By applying the effective voltage formula correctly, you can calculate the equivalent voltage in an AC circuit and gain insights into its power characteristics, enabling effective analysis and comparison with DC circuits.
