Problem $3\mathrm{.}1$

Fig. $3\mathrm{.}1$ shows two $1-$phase rectifier circuits. Given $v_s=170sinVV,R=10,=45,$ and L is so large that the current $i_0$ may be considered to have negligible ripple. For each circuit, carefully sketch and label, with numerical values, the voltage $v_d$ and the current $i_s.$ Hence, determine and the power factor for each circuit.
