II. Understanding Resistors
A. What is a Resistor?
A resistor is a passive electronic component that limits the flow of electric current in a circuit. Its primary function is to provide resistance, which is measured in ohms (Ω). Resistors are essential for controlling voltage and current levels, ensuring that electronic components operate within their specified limits.
1. Basic Functionality
The basic functionality of a resistor can be understood through Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). This relationship is expressed as:
\[ V = I \times R \]
By manipulating resistance, engineers can control how much current flows through a circuit, which is vital for protecting sensitive components.
2. Types of Resistors
There are several types of resistors, including fixed resistors, variable resistors (potentiometers), and specialized resistors like thermistors and photoresistors. Each type serves a specific purpose in electronic circuits, from simple current limiting to complex signal conditioning.
