A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
What happened unexpectedly when mercury was cooled to near absolute zero?
The mercury lost all resistance and became a superconductor.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor has zero resistance.
What is the difference between superconductors and normal conductors?
Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.
Why copper strips are used in meter bridge wire?
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.

Is A superconductor is A conductor having zero resistance?
Yes, a superconductor has zero resistance.
What resistance does a superconductor have?
An ideal superconductor has exactly zero losses, thus resistance is zero.
What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
If a multimeter reads zero on the ohm scale is this high or low resistance?
zero is low resistance
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()

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.
Does a conductor have zero resistance?
No
What would you expect if resistance of the fixed resistor was zero?
zero
An open fuse has a resistance of?
Zero. There is no resistance on an open fuse because there is no connection between the terminals on the fuse. I beg to differ There is INFINITE resistance in a BLOWN fuse... There is ZERO resistance in a GOOD fuse.
