What makes an object conductor?
A conductor has low electronegativity and has 3 or less electrons in the outer shell of the atom. Conductors let electrons run through them with little to no resistance.
Does electricity flow through conductors?
Yeah... That's what makes it a Conductor and not an Insulator.
When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.
When a conductor is charged the charge moves to the outer surface of the conductor?
True. For instance in a wire, all of the charge is carried on the outside surface of the wire, and not down the center. Why?? Because when the electricity flows down the wire it causes alternating magnetic fields which cause alternating eddy currents within the wire. An eddy current is bascially an electromagnetic area of turbulence, and in this instance makes the flow of electrons easier on the outer edge of the wire. The higher the frequency that the electricity flows through the wire, the stronger the eddy currents and a thinner section of wire will carry the charge.
How does current electricity move?
In a conductive material, the atoms have a number of electrons which freely move back and forth from atom to atom. When an electric potential is applied across the conductor, more electrons start moving in from the negative end. The extra negative charge repels the electrons that are already in the conductor, so they start moving towards the 'positive' end. Electrons are negatively charged, and like charges repel each other. Because there are negatively charged particles (the electrons) moving from negative to positive, we conveniently say that 'current flows' from positive to negative (there are these imaginary positively charged particles), but this is just a concept which makes it easier to think about, and not actually how it works.

What makes silver a better conductor than copper?
Extra electrons.
Why copper is a conductor?
Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.) Because this one lonely electron is all by itself in the outer shell, it can easily separate from the rest of the atom and go roaming around, which makes copper a very good conductor
What makes an element a semi-conductor?
an outer valence shell missing one or more electrons. slightly resistive
What is the primary characteristic of an element that makes it a good conductor?
there is only one electron on the outer shell.
What makes a substance an insulator versus a conductor?
Hi, Answer lies in the electron distribution of the element. In insulator the valence electron in the outer most orbit is not present which in the case of conductor is present so insulators do not have free electron or losely held electron to conduct electricity so they are bad conductor of electricity or in other word they are INSULATORS. hope this answers your question

Why feeder cable is cylindrical hollow?
Since the electrons in a current flow are charged in the same direction, they repel each other. That makes them want to travel on the surface of the conductor. The center of the conductor becomes wasted material, so the preference is to save money and weight, and make it hollow or, for strength enhancement, to make the core out of some other material with a high tensile strength.
Can electricity be ran through solid Chocolate?
Yes ... but it makes a mess as chocolate is a lousy conductor.
How does conductors allow heat to go through?
Heat energy can be transfered through a conductor or medium, in three ways. Radiation, which is how the sun transfers energy, through waves. Convection, which is how wind works, the transfer of heat by mixing particles together. Conduction, which is how your hand warms up when someone touches it. The particles transfer their heat energy to adjacent particles.
What makes a lemon a conductor of electricity?
The acid in the lemon makes it a conductor of electricity.
When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.
