Basic Concepts of Resistors

A resistor is an electrical component that limits or regulates the flow of electrical current in a circuit. It functions by providing resistance to the current, which is measured in ohms. The principles of resistance and Ohm’s Law are fundamental to understanding how resistors work. Ohm’s Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. This relationship is expressed as V = IR, where V is voltage, I is current, and R is resistance ¹.
