c) A three phase-supply is available to drive a separately excited de motor through a three-phase full-wave bridge rectifier circuit connected to the armature terminals. The armature resistance is 0.2 12, and the motor draws a current of 205 A when running at 1750 rpm with an armature voltage of 230 V dc. i. Find the firing angle a under the specified conditions. [3 Marks) ii. Find the firing angle a required for the motor to run at 875 rpm. [11 Marks) VD, MD D3 DS a Var b Load Vo Von VCA ADA AD D2
