Calculate Amplifier Efficiency



Formula

The formula to calculate the Amplifier Efficiency is:

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

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:

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:

Using the formula:

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

The Amplifier Efficiency is 50%.
