AC dielectric cure monitoring, also referred to as Dielectric Analysis (DEA), measures a polymer’s capacitance and resistance, which are bulk properties utilized in the conventional electrical model ...

It is important to understand the characteristics of both AC and DC measurements, as both can probe the cure state of thermosets and composites, so it is vital to have a clear outline of the benefits ...

Alternating Current (AC) systems are analyzed using “phasor algebra” ala Stienmetz. Most engineering students initially learn this technique as it applies to single-phase systems. These training ...

When working on simple DC systems, a small low-cost multimeter from the hardware store will get the job done well enough. Often they have the capability for measuring AC, but this is where cheap ...

Lake Shore Cryotronics’ M81-SSM offers DC, AC and lock-in source and measurement. Synchronous modularity The M81-SSM controller shown with two source modules (left); two measure modules (right); all ...

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with ...

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 ...
