This video explains the role of resistors in electronic circuits and how Ohm’s Law defines the relationship between voltage, ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

This video provides a clear explanation of resistors and their role in electronic circuits. It covers the function of ...

All conductors show some opposition to electric current. This opposition to current is called resistance. A good conductor has low resistance. A poor conductor, or insulator, has high resistance. The ...

The filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it and produces light as a result. Taking ...

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Editor’s note: I am so happy that there are still companies around that create precision, discrete transistors in our industry; Linear Integrated Systems is one of the best I have encountered. There ...

APDs (avalanche photodiodes) or APDs, are common components in laser-based fiber-optic systems for converting optical data into electrical form. The bias voltage and current measurement requirements ...

When an electric current passes through the body, it can cause three main effects: When it comes to current, DC becomes hazardous at around 130 milliamps (mA)—a seemingly small amount, especially ...
