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 ...

Current regulators (non-switchable and switchable) are a new family of useful and versatile devices targeted for use in communications, networking and power conversion circuits. Current regulators (or ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

Several types of devices are employed in electronic systems to protect against voltage transients, power surges, and excessive voltage or current. Varistors is one of those devices that protect ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.
