Quizplus · Accepted Answer

The power delivered to the speaker can be calculated using the formula P = V^2 / (2 * R), where V is the peak-to-peak voltage divided by 2 (to get peak voltage), and R is the resistance. For an 8 Vpp sine wave, the peak voltage is 4 V. Therefore, P = (4^2) / (2 * 16) = 0.5 W.
