REMARKS Notice how the concept of rms values allows the handling of an AC circuit quantitatively in much the same way as a DC circuit. QUESTION The rms current in an AC circuit: (Select all that apply.) reverses direction many times per second. is an average current, and is therefore zero. measures the magnitude of the current, as a special kind of average. is the direct current that dissipates energy at the same rate as the AC current.
