QUESTION $2$

Two transformers have the following particulars:

$\backslash$table$[[,$Transformer P$,$Transformer Q$],[$Rated current,$200$ A$,600$ A$],[$Per unit resistance,$0\mathrm{.}02,0\mathrm{.}025],[$Per unit reactance,$0\mathrm{.}05,0\mathrm{.}06],[$No load emf,$245$ V$,240$ V$]]$

Calculate the terminal voltage when they are connected in parallel and supply a lead impedance of $(0\mathrm{.}25+j0\mathrm{.}1).(20$ marks$)$
