Amplifier Efficiency Calculator

Formula

The formula to calculate the Amplifier Efficiency is:

$Eamp = \left(\frac{O}{I}\right) \times 100$

Where:

$Eamp$ is the Amplifier Efficiency (%)
$O$ is the amplifier output power (Watts)
$I$ is the amplifier input power (Watts)

What is Amplifier Efficiency?

Amplifier efficiency is a measure of how effectively an amplifier converts input power into output power. It is calculated by dividing the amplifier output power by the input power, then multiplying by 100 to get a percentage. This efficiency indicates the performance of the amplifier, with higher efficiency meaning less power is wasted as heat.

Example Calculation 1

Let's assume the following values:

Amplifier Output Power (O) = 50 Watts
Amplifier Input Power (I) = 100 Watts

Using the formula:

$Eamp = \left(\frac{50}{100}\right) \times 100 = 50 \%$

The Amplifier Efficiency is 50%.

Example Calculation 2

Let's assume the following values:

Amplifier Output Power (O) = 75 Watts
Amplifier Input Power (I) = 150 Watts

Using the formula:

$Eamp = \left(\frac{75}{150}\right) \times 100 = 50 \%$

The Amplifier Efficiency is 50%.
