$****$please draw and label the circuit$*****$

A $500$W$,200$ V compound motor has two field windings, one has a resistance of $0\mathrm{.}03$ ohms and the other a resistance of $50$ ohms.

$(1)$ Draw and label a circuit diagram. Which winding should be connected to the Z$-$ZZ terminal.

$(2)$ If the armature resistance is $0\mathrm{.}15$ ohms, calculate the emf when it draws an armature current of $5$A whilst running at $3000$ rpm$.$

$(3)$ When the load increases so that the motor draws a current of $10$A$,$ what is the new speed of the machine? $($assume the field shunt current does not change $-$ just the series field$).$
