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 ...

A river made of graphene with the electrons flowing like water. Courtesy: Ryan Allen and Peter Allen, Second Bay Studios Electrons can behave like a viscous liquid as they travel through a conducting ...

Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

In school, you might have learned that electrons were negatively charged and protons were positive. This is not a fact of nature but a human-invented convention. It’s a fact that protons and electrons ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...

Christine and Scott Gable are hybrid auto and alternative fuel experts who have brewed their own biodiesel and traveled 125,000 miles on waste vegetable oil. Electric vehicles rely exclusively on ...
