Hi, everyone, I'm Mwaksy. I'm Greg. Hey.Hey, Greg, so, question.You know how there are electric circuits all around us? Yeah?How is it that we don't get an electric shockwhen we touch the TV or turn ...

Ohm’s law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

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 ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But scientists have now found a way to transform the most widely used polymer, ...

Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

What is an insulator? An insulator is a material that does not conduct electrical current. Insulating materials include paper, plastic, rubber, glass and air. Vacuum is also an insulator, but is not ...

Diamond is an effective electrical insulator, but that might not always be the case according to a new study from MIT and Nanyang Technological University (NTU) Singapore. The team has calculated that ...

All questions and answers are based on the 2011 NEC. Q. What types of equipment grounding conductors does the NEC allow? A. An equipment grounding conductor can be any one or a combination of the ...
