, b) A dc series motor
is operating from 220 V supply. It takes 50 A and runs at 1000 rpm. The
resistance of the motor is 0.1 ohms .If resistance of 2 Ohms is placed in series
with the motor, calculate the resultant speed if the load torque is constant.

Explanation:
How do you calculate armature current of a DC shunt motor?
When dealing with DC motors, sketch the circuit. You know Total Power PT = 11kW and Total Voltage VT = 220V. ...
The shunt field and armature are in parallel. You have the field resistance and the total voltage is applied across the field. ...
Apply KCL to determine Ia.
Not asked, but from there you can calculate back-emf E0.
