Question

Which notation identifies the RMS values of voltage and current?

Options

• \[V=V_{\mathrm{rms}}\] and \[I=I_{\mathrm{rms}}\]

• \[V=v_m\] and \[I=i_m\]

• \[V=\overline{P}\] and \[I=i_m\]

• \[V=i_m\] and \[I=v_m\]

Answer 1

The RMS voltage may be written \[V=V_{\mathrm{rms}}\], and RMS current may be written \[I=I_{\mathrm{rms}}\]. Their corresponding peak values are \[v_m\] and \[i_m\].
