Question $7(1$ point$)$

A separately excited DC generator rotating at $1000$ rpm generates an internal emf of $200$ V when supplied with a field current of $1$ A $.$ The armature resistance of the generator is $1\mathrm{.}5$ ohms. A load that draws an armature current of $10$ A is connected across the generator terminals. If the machine is made to rotate at $1200$ rpm with the same field current of $1$ A $,$ then the terminal voltage $($i$.$e$.$ the voltage across the load$)$ will approximately be
