🔍 Key Concepts

• Relationship between peak, peak-to-peak, and RMS voltage for a pure sine wave • The formula for converting peak voltage (not peak-to-peak) to RMS: ( V_{RMS} = \frac{V_{peak}}{\sqrt{2}} ) • How to correctly find peak voltage when only peak-to-peak is given

💭 Think About

• First, how do you get the peak voltage from a 340-volt peak-to-peak sine wave? What simple division is involved? • Once you have the peak voltage, what constant (involving (\sqrt{2})) do you use to find the RMS value for a pure sine wave? • Estimate the numerical value: is (\frac{V_{peak}}{\sqrt{2}}) closer to 120 V, 170 V, 240 V, or 350 V based on your rough calculation?

✅ Before You Answer

• Be sure you convert peak-to-peak to peak before applying the RMS formula. • Confirm you are using the correct RMS relation for a pure sine wave, not for other waveforms. • Double-check that your final answer is less than the peak value but greater than half of it, as RMS sits between those two for a sine wave.
