Calculate Peak Wattage



Formulas

The formula to calculate the RMS wattage is:

\[ \text{W}_{\text{RMS}} = \text{PW} \times 0.707 \]

Where:

The formula to calculate the peak wattage from peak voltage and current is:

\[ \text{PW} = \text{PV} \times \text{I} \]

What is RMS Wattage?

An RMS value, or in this case, wattage, is a measure of the root mean square of the wattage in a sinusoidal circuit. It provides a more accurate representation of the power delivered to a load compared to peak wattage.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ \text{W}_{\text{RMS}} = 100 \times 0.707 = 70.7 \, \text{W} \]

The RMS wattage is 70.7 W.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ \text{PW} = 50 \times 2 = 100 \, \text{W} \]

The peak wattage is 100 W.
