This video explains the function of diodes and how they are used to control the flow of electrical current in electronic ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...

Do you want to build an electric motor? You could probably find just about everything you need for a simple one around your house. Let me show you how to build it and why it works. Start With Magnet ...

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 ...
