WebAn electrical conductor is a substance which allows electric charge to move through it. An insulator is a substance which does not allow electric charge to move through it. Think back to our model of a metal wire and how the electrons are able to move through the wire. The metal wire is a conductor of electricity. WebTranscript. The positive sign for current corresponds to the direction a positive charge would move. In metal wires, current is carried by negatively charged electrons, so the positive current arrow points in the opposite direction the electrons move. This has been the sign convention for 270 years, ever since Ben Franklin named electric ...

This is easily tested by measuring the resistance of round wires - the resistance will fall quadratically with the radius, indicating that it's the cross-sectional area that matters. Amendment: this answer is only correct for direct current - see Beckett's below for AC. WebIn an electric circuit, the electric potential difference between the two terminals of a battery or energy source provides the electric pressure which presses on charge to move them from a location of high pressure (high electric potential) to a location of low pressure (low electric potential). Energy is required to move the fluid uphill. my online psychologist
