Introduction: Beyond the Charge Storage Model Capacitors are among the most essential components in electrical and electronic systems. Alongside resistors and inductors, they form the foundational elements from which circuit theory is built. From basic power supply smoothing to high-speed digital signaling, radio-frequency communication, and semiconductor device operation, capacitors play a central role in shaping how electrical systems behave. Despite this importance, capaci

Understanding Charge Control and Semiconductor Behavior Transistors are everywhere, which is exactly why they’re easy to take for granted. They sit quietly inside nearly every device you use, and they do their job so well that most people never need to think about what’s happening inside them. But inside a transistor, the “simple” idea of switching and amplifying turns into something far more interesting: you’re shaping electric fields, rearranging charge populations, bending
