What is an Electronic Circuit? An electronic circuit is a complete path through which electricity can flow to power components. It is made up of components like resistors, transistors, capacitors, inductors, and diodes connected by conductive wires or traces through which electric current can flow. The main purpose of an […]

Understanding Corrosion Corrosion is a natural process that occurs when a metal reacts with its environment, resulting in the formation of oxides, sulfides, or other compounds. This process can be accelerated by factors such as humidity, temperature, and the presence of contaminants like salt, acids, or other chemicals. In electrical […]

Introduction to MicroSD Cards MicroSD cards are widely used in various electronic devices, such as smartphones, tablets, digital cameras, and single-board computers like the Raspberry Pi. They provide a compact and reliable storage solution for digital data. Understanding the pinout of a microSD card is essential when interfacing it with […]

What is a Radio Repeater? A radio repeater is an electronic device that receives a radio signal and retransmits it at a higher power, allowing the signal to cover a larger area. Repeaters are commonly used in two-way radio systems, such as those used by emergency services, amateur radio operators, […]

Introduction to Capacitors on Circuit Boards Capacitors are essential components in electronic circuits, playing a crucial role in storing and releasing electrical energy. When it comes to circuit boards, capacitors are widely used for various purposes, such as filtering, smoothing, and decoupling. In this comprehensive guide, we will delve into […]

What is THT Mounting? THT mounting, which stands for “through-hole technology” mounting, is a method of attaching electronic components to a printed circuit board (PCB) by inserting the component leads through holes drilled in the board and soldering them to pads on the opposite side. This is in contrast to […]

Introduction to Heatsinks A heatsink is a passive heat exchanger that transfers heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device’s temperature. In computers, heatsinks are […]

What is a NiMH Battery Charger Circuit? A NiMH battery charger circuit is an electronic device designed specifically to charge NiMH batteries safely and efficiently. The charger circuit monitors and controls the charging process, ensuring that the batteries receive the proper voltage and current while preventing overcharging, which can damage […]

What is a Power Bank? A power bank is a portable battery-powered device that can charge your electronic devices when you don’t have access to a wall outlet. It works by storing electrical energy in its internal battery and then releasing it to your device when needed. Power banks come […]

What is a Kelvin Connection? A Kelvin connection, also known as a four-terminal sensing or 4-wire measurement, is a method used to accurately measure electrical resistance. This technique is particularly useful when measuring low resistance values or when the resistance of the connecting wires is significant compared to the resistance […]
