Q

What is the peak voltage at a common household electrical outlet?

🔍 Key Concepts

• Relationship between RMS voltage and peak voltage in AC circuits • Standard RMS voltage for household outlets in the U.S. • Formula connecting RMS and peak: V_peak = V_RMS × √2

💭 Think About

• First, recall the typical RMS voltage value for a standard household outlet in the U.S. Is it closer to 110–120 volts or 220–240 volts? • Once you know the RMS value, how do you convert RMS voltage to peak voltage using √2 (~1.414)? • After multiplying the RMS value by √2, which of the answer choices is numerically closest to that peak value?

✅ Before You Answer

• Be clear that household outlet ratings (like 120 V) are RMS, not peak values. • Use the correct formula: V_peak = V_RMS × √2, not the other way around. • Check that your calculated peak voltage reasonably matches only one of the choices before selecting.
