All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Hands down — without a doubt, one of the most universally searched topics on EC&M’s website from a historical perspective is “insulation resistance testing.” As a result, some of our most popular ...

Designing circuit boards for high speed applications requires special considerations. This you already know, but what exactly do you need to do differently from common board layout? Building on where ...

Loudspeaker manufacturers sometimes exaggerate the specifications of their products to make them look better than they really are. Some are more honest than others in this regard. The focus of this ...

What if you went to your favorite local restaurant, ordered a meal and the waiter served you 1/2 the portion but charged you full price? Would you feel cheated? Believe it or not,a good deal of home ...

Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

Inadequate shielding and bad grounding are often blamed when measurements are inaccurate, especially in high-impedance applications. In fact, shielding and grounding problems are frequently ...
