Basic Principles of the Carbon Film Resistors in Vietnam | Explained by Selectech
Carbon film resistors in Vietnam are a popular type of resistor widely used in various electronic applications due to their reliability, precision, and affordability. In this blog post, we'll delve into the fundamental principles of carbon film resistors and explore their key characteristics. Construction of Carbon Film Resistors A carbon film resistor consists of a ceramic substrate coated with a thin layer of carbon film. The resistance value is determined by the thickness and width of the carbon film. To adjust the resistance, a spiral pattern is etched onto the carbon film. How Carbon Film Resistors Work When a voltage is applied across the terminals of a carbon film resistor, electrons flow through the carbon film. The resistance of the resistor opposes the flow of current, resulting in a voltage drop across its terminals. The relationship between voltage, current, and resistance is governed by Ohm's Law: V = IR. Key Characteristics of Carbon Film Resistors ● Wide Resis...
