There are three ways to measure voltage in an AC circuit:

Peak voltage: A

measurement of the

largest voltage.Peak-to-peak voltage: The difference between the highest and lowest peaks of the voltage reading.

**RMS voltage**: The average voltage.*RMS*stands for*root mean square*. RMS voltage is the most common way to calculate the voltage of an AC circuit.

DCAClab calculates RMS by sampling the input voltage and doing the sum-of-the-squares, simulating the high quality voltmeters.

Notice the dashed orange line in the oscolicope, its the RMS value of voltage. A good article that explains the math behind RMS can be found here.
