What is the difference between superconductors and normal conductors?
Debostuti
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.

What is the difference between a normal object and a wet object?
weight and saturation.
What is the difference between a wavefront and a ray?
A ray is normal and perpendicular to the wave front. Shortly, that's the difference.
What is the difference between a cantilever chair and a normal chair?
The difference between a cantilever chair and a normal chair is that a cantilever chair is easier movable and more flexible. The chair is however more expensive, but for the features it gives it is worth it.

Make a list of materials which are good conductors of heat and materials which are good insulators of heat from objects at home?
Generally, things that feel cold to touch (in a normal temperature room and no heating applied to them) are good conductors of heat (metals for example). Poor conductors tend to feel neither hot or cold under normal conditions (wood for example).
Which sample of matter are the best conducotors?
The best conductors are superconductors. So far, superconduction has only been achieved at cryogenic (i.e., extremely cold) temperatures.At normal temperatures, the materials that conduct best are metals.
Why are superconductors efficient than ordinary conductors?
It doesn't. Superconductors have no (virtually no) losses, they are purely inductive. This has no bearing on how current flows. Normal conductor will heat up due to resistive losses of the line (I^2 R losses), while a superconductor shouldn't.
What are properties of a superconductors what they are?
A normal conductor has resistance. A superconductor has no resistance. But to make superconductors a very low temperature is required. High-temperature supeconductors require a temperature of minus 203 degrees C, ordinary superconductors require substantially lower temperatures.
What is the difference between a micro pet and a normal pet?
the difference between a micro pet and a normal pet is that a micro pet is a really small animal such as a micro pig and a normal animal is a animal just like a normal person normal size normal wight and that is the difference between a normal animal and a micro animal.
What is the difference between normal saline solution and ringer's lactate solution?
What is the difference between normal saline solution and ringer's lactate solution?
What is the difference between a normal and a participating preference share?
what is defference between normal and preference shares
What is the difference between normal and average respiratory rate?
The difference between normal and average respiratory rate is simple. Normal is healthy and cannot change and average most certainly can change.
What is the difference between sowing and planting?
The treatment effect is the difference between the observed outcome and the "normal" outcome

The treatment effect is the difference between the observed outcome and the "normal" outcome
What is the difference between a normal guitar and a junior guitar?
The difference between a normal guitar and a junior guitar is primarily its size. A Junior guitar is shorter and about three quarters the size of a normal guitar.
