Hello friends! In our previous lessons we tried to explain how fixed and variable resistors are used in the circuit. Through the examples, we analyzed the basic usage principle of these resistors and what their roles are in the circuit. And in this lesson, we will analyze the dependent resistors, which is the last lesson of our range of resistors. Dependent resistors are of three types. These are resistors depending on light, heat and voltage. Now, let’s have a look their structure and how they are used in the circuit.
