QI. A 200 V de shunt motor has R. 1N and Ra 200 2. When running on No-load the current taken is 5A and the speed is 1000rpm. Calculate: (i) The speed when motor is fully loaded and the total current drawn from the supply is 40A. (ii) Explain what will happened to the speed when fully loaded and the shunt field current is reduced by 10%.
