Choose True (V) or false( x) for the following : 4) Reluctance is a measure of "opposition" the magnetic circuit offers to the flux. 5) The rated output power (transformer rating) can be used to determine the turns ratio of the transformer. 6) With the increase in speed of a series DC motor, Both back emf as well as line current increase. 7) When an induction motor is stationary, the stator and rotor windings form the equivalent of a transformer. 8) Increasing the load current for DC Self-excited generator Shunt-Wound Generator will increase the terminal voltage. 9) In lap windings there are as many paths in parallel and used to produce high current, low voltage output. 10) In 3-pahse induction motor, if the rotor speed increases, the rate at which the rotating magnetic field cuts the rotor bars is increasing.
