To calculate the power of an audio amplifier, you can use the formula \( P = \frac{V^2}{R} \), where \( P \) is the power in watts, \( V \) is the output voltage in volts, and \( R \) is the load resistance (usually the speaker impedance) in ohms. Alternatively, if you know the output current \( I \), you can use \( P = I^2 \times R \). It's important to ensure measurements are taken at the amplifier's rated load and within its specified operating conditions.
