Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

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 ...

Article 215 covers the installation, conductor sizing, and overcurrent protection requirements for feeder conductors. The requirements for feeders have some similarities to those for branch circuits.

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...
