When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.
Materials that do not allow electrical charges to pass through it easily are called?
Those are called insulators.
Does an open circuit have a break that interrupts the flow of electrical charges?
Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
A flow of electrical charges is known as an?
A flow of electrical charges running through a medium is known as an electrical current.
Write short note on superconductivity?
A material which has no resistance to electricity. When passing current through a superconductor, there is no loss of electrical power due to these materials.
The opposition to the movement of charges flowing through a material is called what?
RESISTANCE.
What things heat up when electricity flows through them?
Materials with electrical resistance. The heating in any circuit element is by Ohm's Law given by (Current)2 x Resistance. Some materials like silver and copper have very low resistance so little heating.
What is the opposition to the movement of charges flowing through a material?
Resistance
Latex is considered a(n) because charges do not flow freely through it?
If something doesn't let electrical charges to flow through easily, it is called an electrical insulator.
Is the following sentence true or false charges flow easily through every material?
If we're talking about electrical current, then the answer is "false," because an electrical charge will flow very easily through some material, not that easily through some materials, and not at all through other materials. Usually electrical current will flow well through most metals. This is why copper wire is used to carry electricity, because copper allows electricity to flow with little resistance. If EVERY material in the world let electricity flow through it, we would be getting shocked all the time. Plastic and rubber, for instance, are very very resistant to electrical charges. If plastic and rubber allowed electricity to pass in them as easily as copper, you'd get an incredible shock every time you tried to touch your computer, put your finger on a light switch or answered your phone!
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
What are substances that allow electrical charges to pass through them?
Conductors
