How Resistors Work and Their Role in Electronic Circuits

Resistors are fundamental components in electronic circuits that restrict the flow of electrical current. They play a critical role in controlling the voltage, current, and power in electronic devices, and their correct selection and placement are essential for optimal performance. In this article, we will discuss how resistors work and their role in electronic circuits.

What is a resistor? A resistor is a passive electrical component that limits the flow of electrical current in a circuit. It is typically made of a material that offers resistance to the flow of electrons, such as carbon, metal, or ceramic. Resistors come in various shapes, sizes, and values and are used in a wide range of electronic applications.

How do resistors work? Resistors work by converting electrical energy into heat as the current flows through them. They offer resistance to the flow of electrons, which causes a voltage drop across the resistor. Ohm’s law, which states that the current flowing through a resistor is directly proportional to the voltage across it and inversely proportional to the resistance, governs the behavior of resistors in a circuit.
