What is a fully controlled rectifier?

A controlled wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Controlled wave rectification converts both polarities of the input waveform to DC (direct current), and is more resourceful.

What is the difference between simple dc motor and servo motor?

DC motor : -DC (Direct Current) Motors are two wire (power & ground), continuous rotation motors. -The speed of DC motors is controlled using pulse width modulation (PWM), a technique of rapidly pulsing the power on and off. The percentage of time spent cycling the on/off ratio determines the speed of the motor, e.g. if the power is cycled at 50% (half on, half off), then the motor will spin at half the speed of 100% (fully on). Each pulse is so rapid that the motor appears to be continuously spinning with no stuttering. Servo Motor : -Servo motors are generally an assembly of four things: a DC motor, a gearing set, a control circuit and a position-sensor (usually a potentiometer). -The position of servo motors can be controlled more precisely than those of standard DC motors, and they usually have three wires (power, ground &). Power to servo motors is constantly applied, with the servo control circuit regulating the draw to drive the motor. -PWM is used for the control signal of servo motors. However, unlike DC motors it's the duration of the positive pulse that determines the position, rather than speed, of the servo shaft.


Why is a sag provided in the transmission line?

Sag is provided in transmission lines in order to lessen the tension of the transmission lines. Sag literally means to be bend in shape. In overhead transmission lines , the difference in level between points of supports (towers or utility poles) and the lowest point on the conductor is called a sag. Explanation: While erecting an overhead line, it is very important that the conductors are under safe tension. If the conductors are too much stressed between the supports ( towers, utility poles), then the stress on the conductors may reach to an unsafe level and the conductor may break due to excessive pressure ( i,e tension). in order to permit safe tension in the conductors, the conductors ( i.e the transmission lines) are not fully stretched but are allowed to have a dip or a sag.
