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.
