Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

Q. The Code prohibits "objectionable currents;" what is this, what are some examples, and how can it be prevented? A. Section 250.6 of the 2011 NEC addresses objectionable current. First of all, the ...

What's the harm in objectionable current, and how do you eliminate it? You should know 250.6 says objectionable current is not to flow on grounding and bonding paths, but do you know what it is, why ...

The hindrance to the flow of electric charge is known as Resistance. The obstruction posed in the way of current carrying particles by fixed particles creates resistance in an electric circuit. Since ...

If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

We’re surrounded by electrically powered devices these days. From our lights, to our kettles, and of course our phones! Electricity flows through copper or aluminium wire to power or charge all of ...

The components in a home audio/video system are pretty complicated to anyone without a good understanding of electronics; but wire–good, old-fashioned wire–is something we can all understand. It’s ...

Whenever electrical current flows through a conductor, an electromagnetic field is induced around that conductor. For many years, some people have been claiming that these electromagnetic fields cause ...
