What else can I help you with?
Why do you measure emf with a potentiometer not with voltmeter?
EMF (E''electromotive Force'') is another term for Volts, hence the E in electronic formulas and EMF is measured with a volt meter. A potentiometer is not a meter at all, it is a variable resistor
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
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...
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 is the definition of distribution balance point?
The balance point is where a scale can balance equally.
Define potentiometer?
A dual potentiometer is nothing but a potentiometer which has TWO channels.. Like two INs and two OUTs on the same unit.
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.
Why potentiometer is called passive transducer?
because potentiometer generate a own current
How many pages does Balance Point have?
Balance Point has 333 pages.

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.
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.
What is sensitivity of a potentiometer?
Sensitivity of potentiometer means~ smallest potential difference that can be measured with the help of it.
What is the wiper contact of linear potentiometer represent?
The wiper sets the effective resistance of the potentiometer.
