Frequently asked questions

What is the RMS value used for?: Root-mean-square (RMS) voltage or current tells you the effective power of an AC signal. Mains electricity (e.g. 120 V / 230 V) is quoted in RMS.
What is angular frequency?: Angular frequency ω = 2πf, measured in radians per second. It's often more convenient in equations than ordinary frequency f.
