II. Understanding Resistors
A. What is a Resistor?
1. Function and Purpose
A resistor is a passive electrical component that resists the flow of electric current. Its primary function is to limit current, divide voltages, and dissipate energy in the form of heat. Resistors are characterized by their resistance value, measured in ohms (Ω), which determines how much they resist current flow.
2. Basic Principles of Resistance
The principle of resistance is based on 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) of the conductor. This relationship is expressed as:
\[ V = I \times R \]
Understanding this principle is crucial for designing and analyzing electrical circuits.
