Bourns PTA4553-2015CPB103 Resistor Trimmers, Potentiometer and Rheostat

Hello friends! In our previous lesson, we studied the basic duty of fixed resistors in the circuit. We have seen how these resistors are used in the circuit through Ohm's Law. We mentioned that we will study the resistors in three groups. In this lesson, we will study the variable resistors. Variable resistors are of three types. These are Potentiometers, Trimpot and Rheostat. Let's analyze their structure and how they are used in the circuit. There are two types of circuit symbols used for variable resistors. It is possible to see the use of both of these symbols. There is an arrow indicating that the fixed resistor symbol can be adjusted. We can start with the potentiometer. Potentiometers have 3 pins. The maximum resistance value is written on it and the resistance value can be adjusted manually by this shaft. For example, 10KΩ is seen on the potentiometer you see here. This potentio
