In circuits, this usually means …
AC Voltage and Current: alternating current.
They call this Vrms, the "root mean square" voltage. VRMS ≡ V (2)Average From its definition (just square both sides): Vrms^2 = V^2(ave). Now, plugging in my result above for V^2(ave) = (1/2) V0^2 gives Vrms = V0 / Sqrt[2] . The rms voltage is not the average voltage (which is 0), but it''s kind of a "representative" voltage.
