need working for the question 21.(a) A load receives 400 V through a transmission line. The line current is 20A. The powerfactor is 0.9. The transmission line has a resistance of 1 Q.(i) Calculate the power loss in the transmission line.(ii) Calculate the active power delivered to the load.(iii) Calculate the reactive power delivered to the load.(b) A single-phase transformer is rated at 200V/1000V. The secondary voltage of thetransformer is v(t) = 1400 cos (100nt + 7/3) V when a load of 100 2 is connected.(i) Calculate the primary RMS voltage.(ii) Calculate the load reflected on to the primary side.(iii) Calculate the power delivered to the load.(c) A DC motor, which is supplied by a 30 V DC power source, is operating at a constantmotor speed of 600 rpm. The motor has an armature resistance of 0.2 and a back-emf of 28 V. Determine the following:(i) The current drawn by the motor.(ii) The torque produced by the motor.(iii) The power loss in the armature.
