At its core, a resistor is a device that resists the flow of electric current. The basic function of a resistor is to control the amount of current that passes through a circuit, which is essential for protecting sensitive components from damage due to excessive current. The relationship between voltage (V), current (I), and resistance (R) is defined by Ohm's Law, which states that V = I × R. This fundamental principle underpins the operation of resistors in various applications. B. Types of Resistors Resistors come in several types, each designed for specific applications: 1. **Fixed Resistors**: These resistors have a constant resistance value and are the most common type used in circuits. They are available in various resistance values and power ratings. 2. **Variable Resistors**: These include potentiometers and rheostats, which allow users to adjust the resistance value.
