A 120 volts shunt motor draws a current of 75 Amperes at rated load. The armature and shunt field resistances are 0.52 and 502, respectively. A multi tap starter rheostat is inserted in the armature circuit to limit the starting current. If the rheostat has a resistance of 22, determine the percentage tap used such that the starting current will be limited to 150% of its full-load value.
