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 ...

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 ...

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.

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.

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

Article 210 contains the requirements for conductor sizing, conductor identification, overcurrent protection, and GFCI and AFCI protection of branch circuits. It also contains requirements for ...

Electrical system designers have at their disposal several types of fire resistive systems that comply with specific Code requirements. It can be helpful to ...

Heat pumps are energy-efficient and reduce emissions; we turned to experts to determine if one will work in your home.

Cyrus F. Hirjibehedin is in the Quantum Information and Integrated Nanosystems group, Lincoln Laboratory, Massachusetts Institute of Technology, Lexington, Massachusetts 02421, USA. Although computers ...

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 ...
