What is the difference between super conductor and perfect conductor?
A perfect conductor will have absolutely no losses. A super conductor will be essentially lossless if it can be kept at a specific temperature. As it deviates from this temperature, its' losses will increase.
A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
Why is the potential difference between two points in a good conductor so small that it can be neglected?
Potential difference V = I R. Here I is the current passing through the conductor. R is the resistance of the conductor. In case of good conductor the resistance will be almost zero and so the product too becomes almost zero. Hence the potential difference is neglected.
Electron move without potentiel difference in a conductor?
No. In a good conductor you simply need less potential difference than in a bad conductor, to get the same current. But if you have zero voltage, you will also have zero current. Unless you have a superconductor (zero resistance), and the current is already flowing.
Which resistor is the beat conductor 150 or 600?
We're guessing that you meant to type "best", that you typed "beat" instead, and that you then didn't take the trouble to proofread your own typing. A resistor with a lower resistance is the better conductor. The resistance of a perfect conductor is zero ohms.
What do you mean by resistivity?
Zero resistance would be a perfect conductor where the electrons move freely without any losses.
Which substance is the best conductor of elictricity?
Those are the so-called "superconductors" (there are several types), which have ZERO electrical resistance.
What is a zero-conductor?
A zero-conductor is also known as a negative supply conductor.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor is a material that can conduct electricity without any resistance at very low temperatures. This means that once a current is applied, it can flow indefinitely without any loss of energy due to resistance.
What must happen for a superconductor to work?
Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of mercury it will be 4.2K.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What affects the resistance of an electric conductor?
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.
