A separately excited dc generator, when running at $1000$ rpm $,$ supplied $200$ A at $125$ V $.$ The resistance of the armature is $R_a=0\mathrm{.}04$ and the brush voltage drop is $V_{\text{d}\text{r}\text{o}\text{p}}=2V.$

$($a$)$ Draw the schematic diagram of the generator.

$($b$)$ Determine the load resistance, $R_L.$

$($c$)$ Determine the induced emf, $E_{a1}.$

$($d$)$ The speed of the generator drops to $800$ rpm $.$

$($i$)$ Determine the new induced emf, $E_{a2}.$

$($ii$)$ Determine the armature current, $I_a.$

$($e$)$ Determine the new terminal voltage.
