🔍 Key Concepts

• Relationship between peak, peak-to-peak, RMS, and average values of a pure sine wave • What you actually SEE and can easily read directly on an oscilloscope screen • How many points on the waveform you must identify to measure each type of voltage

💭 Think About

• For each option, ask yourself: how would I physically place the oscilloscope cursors or graticule lines to get that value? • Which quantity requires the least calculation and uses the most obvious visible features of the sine wave? • Which of these values (RMS, average, etc.) is NOT directly obvious from just looking at the shape without doing math?

✅ Before You Answer

• Identify which choice uses the maximum and minimum visible extremes of the waveform • Decide which options would normally require mathematical conversion from a measured peak value for a sine wave • Confirm which value you could determine quickly and accurately even if the waveform is slightly noisy or the frequency is changing
