How Resistors Work? How to Use a Resistor | Basic Electronics

In this lesson, I will try to explain you the types of resistors used in almost all electrical and electronic circuits. As in other circuit devices, there are many types of resistors. We will study what these are and how they are used. The unit of the resistors are ohms and they are indicated with the letter R in the circuit. As you can see here, we can analyze the resistors in three groups: Fixed Resistors, Variable Resistors and Dependent Resistors. Variable and Dependent resistors are also available in different versions.
