This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

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

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...
