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%

How can the resistance of a potentiometer be adjusted to control the volume of a speaker?
The resistance of a potentiometer can be adjusted by turning the knob or slider on the potentiometer. By changing the resistance, the volume of the speaker can be controlled.

Explain the principle of null-method of measurement?
The null method is used in measuring the unknown EMF of batteries. The method is about using a potentiometer circuit with the battery of a known and then an unknown EMF connected to it one after the other and locating, in each case, the position of the 'null point'; the point on the potentiometer circuit where the current through the battery is zero.
The potentiometer is which type of tranducer?
The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.
