Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, ...

President Donald Trump took credit for winning the Nobel Prize in Physics, which was awarded this month to three scientists.

Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

How do the circuits of the human brain work—and what happens when they are disrupted? To investigate these questions, ...

Watch this video to learn more about what an electrical circuit is and how it works. Electrical energy flows around circuits which are loops made of metal wires. In this game, touching the wire with ...

People have been using pens to jot down their thoughts for thousands of years but now engineers at the University of Illinois have developed a silver-inked rollerball pen that allows users to jot down ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...
