As we said last month, electrical theory underlies everything we do in the electrical construction business. It is therefore necessary to review this theory regularly. We continue now with Ohm's Law.

What is resistance? The most common definition of resistance is the opposition to current flow—more specifically the flow of electric charge in a material. The circuit element used to model this ...

Do you ever wonder how much of what we do you could figure out from scratch? Tying your shoe might seem simple now, but kids have trouble mastering the skill, and dreaming it up for the first time is ...

It is hard to get very far into electronics without knowing Ohm’s law. Named after [Georg Ohm] it describes current and voltage relationships in linear circuits. However, there are two laws that are ...

Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience. Often, you must wade through myriad specifications, test methods, and claims without fully ...

Termination – the term brings to mind different values of resistance to different specialties in electronics. RF designers think about 50 ohm, video designers 75 ohm, audio and telecommunication ...

Identical except for package type, the PVY117 and PVY117-T microelectronic relays (MERs) specify a maximum on resistance below one ohm at 0.95Ω. With no moving parts, the solid-state relays prove to ...

Megger now offers a digital low resistance ohmmeter that can deliver reliable results when using long test leads. The DLRO2, a 2 Amp handheld tester, is ideal for use in production line testing and ...
