Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...

A 240-volt service powers heavy-duty appliances like ovens, air conditioners, water heaters and electric dryers. If something goes wrong in that panel, it may cause those systems to fail, damage the ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to start with. This box represents your circuit. Notice there is only one path: the perimeter of the ...

Low-frequency signals appearing on the power lines—so what? The level is low relative to the primary power for an AC-powered device. And DC-powered systems are designed to function with wide variance ...

Diagnostic equipment manufacturer TOPDON has launched a professional-grade circuit tester for the European aftermarket.

Cables—the nemesis of compliance, the antennas no one wants—often are the culprits or unwanted stepchildren in EMC testing. Controlling conducted emissions is an inherent problem that requires ...
