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.
Superconductors can conduct electricity without resistance, whereas normal conductors have resistance. Superconductors must be cooled below a critical temperature to exhibit zero resistance, while normal conductors do not require such cooling. Additionally, superconductors can expel magnetic fields from their interior, a property known as the Meissner effect, which normal conductors cannot do.

What are good conductors under normal conditon?
Good conductors of electricity under normal conditions include metals such as copper, silver, and gold. These materials have a high density of free electrons that can move easily in response to an electric field, allowing for efficient electrical conduction.
What is the difference between a cantilever chair and a normal chair?
A cantilever chair has a single leg or support underneath the seat, causing it to flex and bounce when sat on. In contrast, a normal chair typically has four legs for stability. Cantilever chairs offer more flexibility and movement, while normal chairs provide more traditional support.
Is there a difference between laserjet paper and normal paper?
Yes, there is a difference between laserjet paper and normal paper. Laserjet paper is specifically designed for use with laser printers, and it is smoother and more heat-resistant than normal paper. This allows it to produce sharper and more vibrant prints with less risk of jamming or smudging.
Is it normal to have a five degree temperature difference upstairs when using central air conditioning?
Yes, it is normal to have a slight temperature difference between upstairs and downstairs when using central air conditioning. This can happen due to various factors such as poor insulation, air leaks, or the natural tendency of hot air to rise. A five degree temperature difference is generally considered within a normal range.
Make a list of materials which are good conductors of heat and materials which are good insulators of heat from objects at home?
Good conductors of heat include metals like aluminum, copper, and iron, as well as water. Good insulators of heat include materials like wood, plastic, rubber, and ceramic. These materials are commonly found in various objects within the home, such as cooking utensils and insulation materials.
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 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 the difference between a pie and tartlet?
The treatment effect is the difference between the observed outcome and the "normal" outcome
What is the difference between sowing and planting?
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.
