In the circuit shown, ${\mathit{V}}_{\mathit{s}}$ is a $10\mathit{V}$ square wave of period, $\mathit{T}=4\mathit{m}\mathit{s}$ with $\mathit{R}=500\mathit{\Omega }$ and $\mathit{C}=10\mathit{\mu }\mathit{F}$. The capacitor is initially uncharged at $\mathit{t}=0$, and the diode is assumed to be ideal. The voltage across the capacitor $\left({\mathit{V}}_{\mathit{c}}\right)$ at $3\mathit{m}\mathit{s}$ is equal to _________ volts (rounded off to one decimal place).
