A shunt compensating device $($as shown below$)$ is used for reactive power compensation to keep the magnitude of $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_{\text{b}\text{u}\text{s}}$ at $1\mathrm{.}0$ pu $.$ If the reactance $x$ in the figure is $0\mathrm{.}02$ pu $,$ and $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_{\text{c}\text{o}\text{n}\text{v}}$ has a magnitude of $1\mathrm{.}195$ pu and is in phase with $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_{\text{b}\text{u}\text{s}}$

a$.$ draw a phasor diagram to show the phasors $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_{\text{b}\text{u}\text{s}}\frac{,}{b}ar(V{)}_{\text{c}\text{o}\text{n}\text{v}}$ and $\frac{?}{\text{b}\text{a}\text{r}}(I{)}_{\text{c}\text{o}\text{n}\text{v}}$

b$.$ does $\frac{?}{\text{b}\text{a}\text{r}}(I{)}_{\text{c}\text{o}\text{n}\text{v}}$ lead or lag $\frac{?}{\text{b}\text{a}\text{r}}(V{)}_{\text{b}\text{u}\text{s}}?$

c$.$ how much reactive power $($in pu $)$ is delivered by the compensation device?
