CFR-50JB-52-15R Resistors highlighting the core functional technology articles and application development cases of Resistors that are effective.
Core Functional Technology of Resistors
1. Basic Functionality: Resistors are fundamental components in electronic circuits, primarily used to limit current flow and divide voltages. They operate based on Ohm's Law, where the voltage (V) across a resistor is proportional to the current (I) flowing through it, with the resistance (R) being the proportionality constant (V = I × R).
