A dc motor rated for 48 V has its armature resistance of 0.4 Ω. The speed-emf constant of the motor is 0.3 V/(rad./s). The motor drives a constant load (independent of speed) of 1.2 Nm. Determine the armature voltage (in V) that needs to be applied in order to operate the motor at a speed of 1000 rpm. Do the calculations correct to 1 decimal place
