Template:Half-wave rectifier voltage

THESE ARE EXPRESSIONS FOR HALF-WAVE RECTIFICATION, NOT FULL-WAVE. PLEASE DO NOT CHANGE TO TO SQUARE-ROOT 2. You will be completely wrong and will be reverted.

${\begin{aligned}V_{\mathrm {rms} }&={\frac {V_{\mathrm {peak} }}{2}}\\[8pt]V_{\mathrm {dc} }&={\frac {V_{\mathrm {peak} }}{\pi }}\end{aligned}}$
