Peak and RMS Values of Sinusoidal AC Voltages (VCE SSCE Physics): Flashcards

Root-mean-square

Maximum voltage reached during one AC cycle

$V_p = V_{ ext{rms}} \times \sqrt{2}$

1.414

325 V

$V_{p-p} = 2 \times V_p$

$I_{\text{rms}} = \frac{I_p}{\sqrt{2}}$

$P_{\text{effective}} = V_{\text{rms}} \times I_{\text{rms}}$

$P_{\text{effective}} = \frac{V_p \times I_p}{2}$
