We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

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 ...

An electric circuit is a complete path of conductor from one terminal of a battery to the other. The following symbols show the different components that can be found in an electrical circuit. A ...

Electric current is caused by moving electric charges. The effects of charge and electric fields can be investigated by looking at the forces they exert on conductors and insulators. Simple circuits - ...

The film explains the fundamentals of electricity, including static and current electricity, the behavior of electrons, and the concept of electrical circuits. It demonstrates how static electricity ...

Inside nearly every electronic device is a simple coil of wire doing a powerful job—it’s called an inductor. Though small and ...

The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.
