A sine wave's peak is measured at 30 volts. What is its peak-to-peak value?

• A. 3.3 volts
• B. 15 volts
• C. 21.21 volts
• D. 60 volts

Answer: (D)

The peak-to-peak value of a sine wave is calculated by taking the total distance from the highest point (peak) to the lowest point (trough) of the wave. For a sine wave, the peak value is half of the peak-to-peak value. In this case, if the peak is given as 30 volts, the peak-to-peak value is simply twice that amount. Therefore, you would calculate it as 30 volts (the peak value) multiplied by 2, which gives you 60 volts as the peak-to-peak value. This understanding is essential in many applications involving AC signals, where differentiating between peak, root mean square (RMS), and peak-to-peak values is crucial for proper equipment operation and calibration.
