Problem $8\mathrm{.}43$

You have been asked to design a full$-$wave bridge rectifier for a power supply. A stepdown transformer has already been chosen. It will supply $12$ V rms to your rectifier. T he full$-$wave rectifier is shown in the circuit of Figure P$8\mathrm{.}43.$

a$.$ If the diodes have an offset voltage of $0\mathrm{.}6$ V $,$ sketch the input source voltage $v_s(t)$ and the output voltage $vo(t),$ and state which diodes are on and which are off in the appropriate cycles of $v_s(t).$ The frequency of the source is $60$ Hz $.$ Ohm

b$.$ If $R_0=1,000$ and a filtering capacitor has a value of $8F,$ sketch the output voltage vo$($t$).$

c$.$ Repeat part $($b$),$ with the capacitance equal to $100F.$
