The PIC is powered by a large capacitor while the triac is conducting, preventing it from resetting until the circuit can start stealing power again. Pretty clever stuff, and a nice PCB design to ...

In this course, you will learn the purpose of each component in an equivalent-circuit model of a lithium-ion battery cell, how to determine their parameter values from lab-test data, and how to use ...

In microwave engineering, it is sometimes required to approximate electrically short transmission lines with an equivalent Pi-network. This kind of equivalent network of the short transmission line is ...

The first component is an optocoupler which isolates your control circuit from the mains power that you are controlling. Second, a triac ... more heat than an equivalent mechanical relay.

Two other common optocoupler outputs are SCR and triac. Both types feature high current-transfer ratios and are typically used to control higher voltage AC circuits. Opto-isolated SCR devices use a ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

The US Court of Appeals for the Federal Circuit affirmed a district court determination that a patent owner had not provided the ...

Stars from high-profile entries like “Baby Reindeer,” “Fargo,” “True Detective: Night Country” and more are in the running for this year’s Emmy race in best limited series… ...

The value of a tax-equivalent yield to an investor depends on an individual's tax bracket. The tax-equivalent yield is the return a taxable bond needs to equal the yield on a comparable tax-exempt ...

In this episode of The Circuit, Emily Chang visits the defense entrepreneur who argues companies like his are critical to America’s future. In this episode of The Circuit with Emily Chang ...

Designers can make useful products that include electrical components close electrical componentA device in an electric circuit, such as a battery, switch or lamp.. They allow a product to have ...
