Consider the following statements for the pneumatic and hydraulic systems:1. The normal operating pressure of pneumatic control is very much higher than that of hydraulic control.2. In, pneumatic control external leakage is permissible to a certain extent, but there should no leakage in a hydraulic control.Which of the statements given above is/are correct?
In case of DC servomotor the back-emf is equivalent to an “electric friction” which tends to :
Assertion (A): In the error detector configuration using a synchro transmitter and synchro control transformer, the latter is connected to the error amplifier.Reason (R): Synchro control transformer has almost a uniform reluctance path between the rotor and the stator.
Assertion (A): In a shunt regulator, the control element is connected in shunt with the load to achieve constant output voltage.Reason (R): The impedance of the control element varies to keep the total current flowing through the load and the control element constant.
Assertion (A): The stator winding of a control transformer has higher impedance per phaseReason (R): The rotor of control transformer is cylindrical in shape.
