A dc series motor is connected to a load. The torque varies as the square of the speed.With the diverter-circuit open, the motor takes 20 A and runs at 500 r/min. Determine the motor current and speed when the diverter-circuit resistance is made equal to the series-field resistance. Neglect saturation and the voltage drops across the series- field resistance aswell as the armature resistance.
Draw the implementation of time-invariant system A linear time-invariant system is described by the difference equation: y[n] = 2x[n] - 3x[n - 1] + 2x[n - 2] Draw the i
