In practice means this, the load returns the delivery at no time energy to the amplifier. In zero by the voltage is also the power zero, in the maximum of the voltage reachs also the power its maximum. In this case reaches the power at 125 milliseconds the maximum of 12,5 Watt.

Power = Voltage^2/Load Resistance For example an amplifier that is rated to deliver 50 watts RMS into an 8 ohm load would be 50=Voltage^2/8 or 400=Voltage^2. Solving the equation, we find that 50 watts into an 8 ohm load means our amplifier is …
How will an audio power amplifier output voltage behave ...

In general, the output voltage of an Audio Power Amplifier remains fairly constant as the load changes. The changes in output voltage as the load is varied occur for several reasons: resistance between where the negative-feedback point is in the amplifier to the output terminals, how much negative-feedback is actually used inside the amplifier, some other (minor) factors.

8V x 8V / 4R = 16 Watt. Therefore many vehicle sound systems use bridge amplifiers to power speakers. A popular belief is that 4 times the power is achieved from bridging 2 amplifiers in comparison to single ended application. This is partially true, but there is no such thing as something for nothing.

O(RMS) = 2 x 4, which means that the RMS output voltage from the audio power amplifier must be 2.83 V. Because the peak-to-peak output voltage of the CODEC is 3 V, convert this to RMS voltage,

That is a defensible answer and it is why many mixers and DSPs use this (or a close value) as their “nominal” input and/or output level. It’s also why most professional power amplifiers use 1.2 Vrms (or a close value) as their input sensitivity, as it will drive the amplifier to its full output voltage.
