Potentiometers work by having a resistive element inside. Both end terminals are attached to it, and do not move. The wiper travels along the strip when the knob is turned. The closer the wiper is to the end terminal it is wired in conjunction with, the less the resistance, because the path of the current will be shorter. The further away it moves from the terminal, the greater the resistance will be.
The symbol for a potentiometer is the same one as a resistor, save for an arrow in the middle. In a circuit where they are used strictly as variable resistors or rheostats, only two terminals are wired to the other components. All three terminals are wired separately when they function as voltage dividers. Light dimmers in houses and volume controls on electronics are two common applications. Others include switches and position sensors

What is Direct potentiometry?
Direct potentiometry is a method of measuring the concentration of ions in a solution by directly measuring the potential difference between an ion-selective electrode and a reference electrode. It is a simple and rapid technique that is commonly used in the analysis of various ions in solutions.
What is the advantage of potentiometry?
Potentiometry is a field of electroanalytical chemistry in which the potential of a solution is measured with no current flow; there are many different methods of doing this and structures of potentiometers in existence. It is used to determine the concentration of different analyte ions in solution. This can have many practical applications; potentiometry is used to determine the end-point of titrations, the amount of fluoride in drinking water, and the pH of solutions, among many other things.
Who was the first person to apply the principles of forensic science to a working crime laboratory?
Edmond Locard was the first person to apply principles of forensic science to a working crime laboratory. He applied what is called the Locard's exchange principle to a working crime laboratory.
What is the use of platinum electrode in potentiometry titration?
Platinum electrode is used as the indicator electrode in potentiometry titration to measure the potential difference between the indicator electrode and the reference electrode. It provides a stable and reproducible potential during the titration process, allowing for accurate determination of the equivalence point. Platinum electrodes are inert and do not participate in the redox reactions happening during the titration, making them suitable for a wide range of titrations.
Who was the first person to apply the principle of forensic science to a working laboratory?
Dr. Edmond Locard, a French forensic scientist, is credited with being the first person to apply the principles of forensic science to a working laboratory setting. Locard also established the world's first forensic laboratory in Lyon, France in 1910.
