The time characteristic of an alternating voltage \(u\) is given in the figure. Find the effective value \(U\) of the alternating voltage \(u\) provided the following relation holds: \(U^2T=\int_0^T u^2\mathrm{d}t\).
\( U=325\,\mathrm{V}\)
\( U\doteq 230\,\mathrm{V}\)
\( U=0\,\mathrm{V}\)
\( U=\frac{325}2\,\mathrm{V}\)
