🔍 Key Concepts

• Relationship between RMS (root mean square) voltage and peak voltage for a sinusoidal AC waveform • Standard formula: ( V_{\text{RMS}} = \frac{V_{\text{peak}}}{\sqrt{2}} ) for a pure sine wave • How to find the multiplying factor to go from RMS (what the meter shows) to peak value

💭 Think About

• If the meter is showing RMS voltage and you want peak voltage, how would you rearrange the formula ( V_{\text{RMS}} = \frac{V_{\text{peak}}}{\sqrt{2}} )? • What is the numerical value of ( \sqrt{2} ) to three decimal places, and how does that compare to the answer choices? • Are the answer choices showing a number greater than 1 or less than 1, and should the factor to go from RMS to peak make the value larger or smaller?

✅ Before You Answer

• Confirm that an AC voltmeter scale for household/marine power normally reads RMS voltage, not peak • Calculate or recall the approximate value of ( \sqrt{2} ) and its inverse 1/( \sqrt{2} ) • Make sure the direction of conversion (RMS → peak) matches a factor that makes the numerical voltage value larger, not smaller
