Resistors are essential components in electronic circuits. Their main function is to limit the flow of current, regulate voltage and current in circuits, and achieve various electrical functions. Resistors come in various types and are widely used in applications ranging from consumer electronics to industrial equipment, automotive electronics, and medical devices. This article aims to explore the main product categories of resistors and their applications, helping readers better understand the importance of resistors in modern electronic technology.
Resistance is the degree to which a material impedes the flow of current, usually represented by the letter "R" and measured in ohms (Ω). The resistance value depends on the material's properties, geometric shape, and temperature.
Ohm's Law is one of the fundamental laws in circuit analysis, showing the relationship between current (I), voltage (V), and resistance (R). The formula is:
\[ V = I \times R \]
This means that under a certain resistance, voltage is directly proportional to current.
Resistors work by converting electrical energy into heat energy. When current flows through a resistor, the atoms inside the resistor vibrate due to the flow of current, generating heat. This heat generation is the main working principle of resistors.
Resistors can be classified according to different standards, here are the main classification methods.
