$8\mathrm{.}40$ Refer to Problem $8\mathrm{.}38$ and assume a load voltage waveform as shown in Figure P$8\mathrm{.}40.$ Also assume:

$|i_o{|}_{\text{a}\text{v}\text{g}}=60mA,|v_o{|}_{\text{a}\text{v}\text{g}}=5V,|V_{\text{r}\text{i}\text{p}\text{p}\text{l}\text{e}}|=5\%$

$v_{\text{l}\text{i}\text{n}\text{e}}=170cos(t)V,=377ra\frac{d}{s}$

Determine:

a$.$ The turns ratio $n.$

b$.$ The capacitor $C.$
