What is the average voltage Vavg of the source?
Understand the Problem
The question is asking for the average voltage of a source. This typically requires an understanding of the context in which voltage is measured, as well as the method used to calculate the average, which may involve integration or summation over a specific time period.
Answer
RMS (root mean square) value.
The final answer is the RMS (root mean square) value in AC circuits.
Answer for screen readers
The final answer is the RMS (root mean square) value in AC circuits.
More Information
In alternating current (AC) systems, the average voltage is often represented by the root mean square (RMS) value because the average of a symmetrical AC waveform over a complete cycle is zero.
Tips
A common mistake is confusing the average voltage with the RMS value for AC circuits. The average voltage of pure AC over a full cycle is zero, but the RMS value is used to represent the effective voltage.
