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%
The potentiometer is which type of tranducer?
The potentiometer is a position tranducer. It forms a resistance divider, proportional to position.
What is resolution of potentiometer?
resolution of petentiometer
Is potentiometer and Thermistor are variable resistors. How please explain?
A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
Which is preferred for measuring emf of a cell avoltmeter or potentiometer?
A voltmeter is used to measure voltage. A potentiometer is used to vary the amount of resistance in a circuit - it has nothing to do with measuring.
Define dual potentiometer?
A dual potentiometer is nothing but a potentiometer which has TWO channels.. Like two INs and two OUTs on the same unit.

What is the senstivity of a potentiometer?
The volt drop across one mm of potentiometer is the sensitivity of the device. If it is calibrated in such a way that each mm of the potentiometer wire has a drop of 0.001 V then it is so sensitive.
Why is copper wire not used in potentiometer?
Copper is not used in potentiometer due to the following reasons: 1)Low resistivity 2) High Temperature Coefficient of resistance

What type of transducer Is potentiometer?
what type of transducer potentiometer
What are uses of potentiometer?
A potentiometer is a variable resistor used in electronics.
What you mean by sensitivity of potentiometer?
Sensitivity of potentiometer: A potentiometer is said to be more sensitive, if it measures a small potential difference more accurately.
Why potentiometer is called passive transducer?
because potentiometer generate a own current
How do you bypass the e break for the dual dvd710?
Easy, Ground it with your stereo ground wire.... (make the pink wire and black wire connect to the Main Ground wire which is also Black)
What is sensitivity of a potentiometer?
Sensitivity of potentiometer means~ smallest potential difference that can be measured with the help of it.
