🔍 Key Concepts

• Relationship between peak-to-peak voltage and RMS voltage for a sine wave • Power formula using RMS voltage and resistance: P = V² / R • Difference between peak, peak-to-peak, and RMS values

💭 Think About

• How do you convert a peak-to-peak voltage reading on an oscilloscope into RMS voltage for a sine wave? • Once you have RMS voltage, how do you calculate power when the load resistance is known? • Are you sure you are using peak-to-peak voltage correctly in the power formula, or do you need to convert it first?

✅ Before You Answer

• Confirm the correct conversion factor from peak-to-peak to RMS for a sinusoidal waveform • Use the correct formula P = V² / R with RMS voltage, not peak or peak-to-peak directly • Double-check your math with units: volts² / ohms should give watts
