At very cold temperatures what loses all resistance to the flow of electricity?
At very cold temperatures, certain materials like superconductors can lose all electrical resistance, allowing electricity to flow through them without any loss of energy. This phenomenon is known as superconductivity.
Why does a heating element get hot when current flows?
The current is doing work against the resistance of the material which makes up the heating element.Because it has resistance.-- Whenever electric current flows through a resistance, it loses energyequal to (current-squared) x (resistance).-- When we connect components in an electrical circuit, we use wire withthe least possible resistance, so as not to lose energy in the wiring.-- When we want to warm up the lab, we use wire with significant resistance,in order to have it dissipate significant energy and radiate heat.
An electrical conductor that has very low resistance to current at low temperatures is called?
You're going for "superconductor", but your appreciation of the phenomenonof superconductivity is fundamentally wrong, and your description is incorrect.A superconductor is not a substance that has very low resistance at low temperature.It's a substance that at sufficiently low temperature loses all resistance, and itsresistance becomes zero. Just plain zero.Once an electric current is circulating in a superconducting loop and the ends of theloop are connected together, the current keeps on circulating without any batteriesor power supply as long as the loop stays cold enough. That can be days, or weeks,or months, during which time the current travels around the entire loop literally millionsof times, without additional input and without loss.
How does a wind turbine lose energy?
A wind turbine loses energy due to factors such as friction in the mechanical components, electrical losses in the generator, and inefficiencies in the conversion of kinetic energy from the wind into electrical energy. Additionally, wind turbulence, blade design, and air resistance can also contribute to energy losses in a wind turbine.
Does a pendulum get slower when it loses momentum?
Yes, a pendulum will slow down as it loses momentum due to the effects of friction and air resistance. This will cause the pendulum's swing to become shorter and take longer to complete.

The use of carbon steel as a cutting-tool material is restricted because?
it loses hardness at high temperatures.

What is a superconductor?
It has no resistance to a electric current
What may happen when a material loses heat?
The temperature of this material decrease.
Why is the efficiency of a transformer less than 100?
Assuming you're asking about an electrical transformer... Electricity meets resistance as it flows threw the transformer. Some of the flow of the energy is converted to heat due to the resistance and you get less electrical energy out than you put in. Think of electrical resistance as similar to friction between two objects, say rubbing your hands together quickly and generating heat.

What is a self demagnetization?
Self demagnetization occurs when a magnetic material loses its magnetic properties over time due to factors such as exposure to high temperatures, physical stress, or external magnetic fields. This results in a decrease in the material's ability to attract or hold a magnetic charge.
What is a material that loses electrons becomes a positively charged b negatively charged cneutral deasilt attracted?
A material that loses electrons becomes positively charged.
When an atom gains or loses electrons it has an electrical charge. It is known as?
It is called an ion.
How does heat affect magnetism?
If one continously heats a particular magnet to high temperatures or long time or both, it loses it magnetism because the particles get excited and start forming no-magnetic arrangements.
