Why the plot for output voltage from potentiometer as shaft position is a straight line?

Because the potentiometer has a linear curve for resistance. This won't be true for non-linear potentiometers, such as in a volume control application, which needs to be logarithmic.

What type of speed control system uses a wire -wound potentiometer?
A potentiometer is another name for a variable resister used for voltage dividing. Potentiometers have three tabs on them The two outer most tabs have the full resistance of the device across them. The center tab is connected to the wiper that slides across the surface of the resister. A voltage is applied to the two outside tabs on the potentiometer. A voltage of your choosing will appear across either the left tab to the center wiper tab or from the right tab and the center wiper tab. A potentiometer of this type is used to control the speed output of variable frequency drives. A 10K potentiometer has 10VDC applied across the two outside tabs If the drive sees the full 10 volts it allows the drive to go to full output and the motor will run at full speed. With the potentiometer's center tab wiper at half position a voltage of 5 VDC will appear to the drive. When the drive sees the 5 volts it tells the drive to go to half speed output and the motor will run at half speed. This potentiometer is linear so no matter where the wiper is positioned, the motor speed will follow the potentiometer settings from 1% right up to 100%
A potentiometer is used for?
A potentiometer is a type of position sensor. They are used to measure displacement in any direction. Linear potentiometers linearly measure displacement and rotary potentiometers measure rotational displacement. Also known as a Potmeter or Pot, it consists of a resistive element called the track and a sliding contact called the wiper internally where end terminals are attached to the resistive element. They are used to accurately measure voltage and help achieve a variable voltage from a fixed-voltage source. Common Examples of Potentiometers are: Measuring Position on a gaming joystick Controlling audio equipment using volume controls
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).

Can a potentiometer detect angle?
Yes, but you need a circuit (a PLC may be of help) to convert the potentiometer output (say 0 V to Vmax) into angles. A conventional potentiometer (linear) powered by a constant voltage power supply will work for angles from 0 to 90 degrees, since the voltage you get will be proportional to the angle sinus, starting from zero up to Vmax @ 90 degrees. For angles from 0 to 180 degrees (or -90... 0... +90 degrees) it will be easier with two power supplies connected in series taking the middle point as zero (Volts). Positive voltages from the potentiometer cursor against zero will be obtained for positive angles and negative voltages for negative angles, but you might need a 360 degrees or multiturn potentiometer. There is the basic idea, the rest is yours...
Is a potentiometer and voltage regulator the same thing?
No. A potentiometer is a variable resistor that allows you to set a voltage ratio or to adjust a resistance in a circuit. A voltage regulator, on the other hand, is a device that responds to changes in load, making automatic correction of output voltage. If you increase the load on a potentiometer, the output voltage will change, but not so (within limits) for a voltage regulator. However, you can use a potentiometer in a voltage regulator to make the output adjustable.
How do you increase output voltage of a alternator?
The voltage output is controlled by the voltage regulator. Check to see if you are getting a DC field voltage. On the voltage regulator there are terminals to different pieces of equipment on the machine. Look for the terminals that are designated F1 and F2. These should have a DC voltage on them. Also look for a potentiometer that controls the field voltage. Turn it one way and the voltage will go down and turned the other way the voltage will go up. Make sure that this potentiometer is in the correct position to allow voltage to the field coils.
What does the trottle position sensor do on a 1992 ford explorer?
The Throttle Sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the Throttle Valve position into output voltage, and emits the voltage signal to the ECU. In addition, the sensor detects the opening and closing speed of the Throttle Valve and feeds the voltage signal to the ECU.
Working principle of servo motor?
Servo motors are geared DC motors with the closed-loop circuitry incorporated within them. The basic configuration of a servo motor composed of a DC motor, gearbox, potentiometer and control circuit.DC motor is used to move a gearbox with a large reduction ratio. The final shaft imposes a force on the external load and simultaneously acts on the axis of the feedback potentiometer. So, the potentiometer senses the position of the axis and sends a corresponding voltage to an operational amplifier. This voltage compared to the input voltage, that determines the desired position of the shaft, producing a voltage in the output of the comparator. This voltage powers the motor such that the shaft moves in the necessary direction to align with the angle that corresponds to the voltage applied to the input.

A potentiometer can act as a voltage divider?
Yes. One leg is connected to ground, the other leg is connected to the input, and the tap is the output.

What causes increase of the output of a generator that should be 220 volt to 400 volt?
It sounds like the field voltage potentiometer is not working or has been turned up. Try turning it down and see if the output voltage goes down with it. If it doesn't then the voltage regulator is not working as the field voltage is regulated from the regulator.
