Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

A quick calculation: To estimate a battery’s internal resistance, you can use a simple voltage-drop method when the open-circuit voltage, loaded voltage, and current draw are known. For example, if a ...

Power integrity is becoming a bigger problem at 10/7nm because existing tools such as static analysis no longer are sufficient. Power integrity is a function of static and dynamic voltage drop in the ...

Inevitably, industrial facilities are going to have 460VAC, 3-phase motor loads. And, of course, since voltage drop is considered mainly a performance issue, maximum voltage drop rules on a circuit ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string of roadway, walkway, or parking ...
