Resistors are essential passive components that limit current flow and divide voltages in electronic circuits. Governed by Ohm’s Law (V=IR), their resistance (R) determines how they control energy as heat (P=I²R). From fixed resistors to variable types like potentiometers, they enable precise circuit tuning, signal attenuation, and protection against overcurrent. Key applications include voltage dividers, LED current regulation, sensor interfacing, and analog signal processing. This guide covers resistor principles, critical calculations, and their role in modern electronics—ensuring stable, efficient circuit operation.

Capacitors are fundamental components in electronics, storing energy as electric field energy between charged plates. Their stored energy can be calculated using three key formulas—E=½CU², E=½QU, and E=Q²/2C—depending on known parameters like capacitance (C), voltage (U), or charge (Q). Factors such as plate area, spacing, and dielectric material influence their storage capacity, while supercapacitors push limits with rapid charge/discharge cycles. Widely used in power systems, renewable energy storage, and electronic circuits, capacitors play a crucial role in stabilizing voltage, filtering signals, and recovering energy. This guide explores capacitor energy principles, critical calculations, and modern applications.
Resistors (commonly referred to simply as "resistors" in daily usage) are current-limiting components. When connected in a circuit, a resistor typically has a fixed resistance value with two pins that restrict the current flow in its connected branch.

PCIM Europe 2025, the global benchmark event for power semiconductors, will take place May 6-8 in Nuremberg, Germany. This year's edition will break new records in scale, focusing on power electronics, intelligent motion, renewable energy, and energy management, while connecting key industries like semiconductors, energy storage, and electric vehicles. Germany's booming market—driven by industrial demand, energy transition policies, and government support—presents major opportunities for Chinese enterprises.
The cost of a PCB board is calculated in the following way: At the time of initial fabrication, there is a one-time photographic fee, which includes printing on the front and back, and one photo for each side.
