Effective Value Calculator for Different Waveforms





Formulas

The formulas to calculate the effective value for different waveforms are:

Sine Wave:

\[ U_{eff} = \frac{U_m}{\sqrt{2}} \]

Triangle Wave:

\[ U_{eff} = \frac{U_m}{\sqrt{3}} \]

Square Wave:

\[ U_{eff} = U_m \]

Pulse Wave:

\[ U_{eff} = \sqrt{\frac{U_m^2 \cdot \tau}{T}} \]

What is Effective Value?

The effective value (also known as RMS value) of a waveform is a measure of the equivalent DC value that would produce the same heating effect in a resistor. Different waveforms have different relationships between their peak and effective values. This calculator provides the effective value based on the waveform type and its peak value.

Example Calculation

Let's assume the following values for a sine wave:

Step 1: Calculate the effective value:

\[ U_{eff} = \frac{10}{\sqrt{2}} \approx 7.07 \text{ V} \]
