Rms for an alternating voltage
The rms potential difference is the AC potential difference which dissipates/produces the same amount of energy as an equivalent DC potential difference.
Rms for an alternating current
The rms current is the alternating current which dissipates/produces the same amount of energy as an equivalent direct current.
