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 ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

AC/DC power supplies are used in several electronic devices, encompassing computers, smartphones, radios, and TVs. AC/DC power supplies come in many dimensions and configurations, tailored to suit the ...

This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...
