🔍 Key Concepts

• Root-Mean-Square (RMS) definition for voltage and current • Relationship between RMS value and heating effect (power) in a resistor • Difference between peak, average, and RMS values in AC circuits

💭 Think About

• Think about how you could replace an AC source with a DC source so that the power (heating) in a resistor stays the same. • Consider which choice talks about a condition that matches what RMS actually measures, not about mathematical operations on peak or average values that sound similar. • Ask yourself: does RMS refer to an instantaneous peak, an average over a cycle, or a specific equivalent effect?

✅ Before You Answer

• Identify which option refers to heating effect in a resistor over time, not just a mathematical manipulation of voltage values. • Check whether the option confuses peak value with RMS value—those are not the same. • Verify that the correct description should match: RMS is equivalent to a DC value producing the same power (I²R) in the same resistor.

Question 1 of 20

What is the equivalent to the root-mean-square value of an AC voltage?

AC voltage is the square root of the average AC value.

The DC voltage causing the same heating in a given resistor at the peak AC voltage.

The AC voltage found by taking the square of the average value of the peak AC voltage.

The DC voltage causing the same heating in a given resistor as the RMS AC voltage of the same value.
