Question

In an industry an engineer is designing a dc shunt machine which behaves as a motor. he is connected an armature resistance of 0.08ω and shunt resistance of 240ω in dc shunt motor. when he gives supply of 240v dc then motor runs at a speed of 1000rpm. initially dc shunt motor works at no-load and motor is taking 5a current. now when he places a load so motor takes 4a current. Calculate speed of motor at no load​
