Enter the power (watts) and the incident wave intensity (W/m^2) into the Calculator. The calculator will evaluate the Effective Area.

## Effective Area Formula

EA = P/I

Variables:

To calculate the Effective Area, divide the power in watts by the incident wave intensity.

Power is the total power being received or transmitted, measured in watts (W). In the context of this formula, it typically refers to the power of a signal or wave.

Incident wave intensity is the power per unit area carried by a wave, measured in watts per square meter (W/m^2). It represents the strength or intensity of the wave as it strikes a surface.

## How to Calculate Effective Area?

The following steps outline how to calculate the Effective Area.

1. First, determine the power (watts).
2. Next, determine the incident wave intensity (W/m^2).
3. Next, gather the formula from above = EA = P/I.
4. Finally, calculate the Effective Area.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

power (watts) = 1245

incident wave intensity (W/m^2) = 454
