Question

What are the disadvantages of potentiometer?

Answer 1

A potentiometer is a voltage divider that consists of a three-terminal resistor with a sliding or revolving contact. It operates as a variable resistor when only two terminals, one end and the wiper, are employed. A potentiometer's circuit determines the exact value of emf. Voltmeters are also used to calculate the voltage in any circuit, as we all know.

Complete step by step solution:
Let’s see the disadvantages of Potentiometer.
It is inconvenient to use a potentiometer.
The cross-sectional area of the potentiometer wire must be uniform, which is almost impossible to achieve.
The temperature of the potentiometer wire must remain constant during the experiment. Because of the current flow, this is problematic.
The main problem is that moving3 their sliding contacts, i.e. wiper, needs a lot of force. Wear and tear are present, as well as movement of the wiper. It shortens the transducer's lifespan.
There is also a limited amount of bandwidth available.

Note:
Let us know a little more about potentiometers. A potentiometer is a measuring instrument that is essentially a voltage divider that is used to measure electric potential (voltage); the component is an embodiment of the same idea, hence its name. Potentiometers are commonly used to control electrical devices, such as volume controls on audio equipment.
