A d.c. series motor draws 25 A from a 260 V line while running at 900 rpm. It has an armature resistance of 1.5 Ω and a series field resistance of 0.8 Ω. A diverter is to be added to the circuit so that the speed increases to 1200 rpm while the line current increases to 30 A. Find the value of the diverter resistance Rd . a) find the Rd mathmatically
