What happens when a circuit is closed?
when a circuit is closed, electricity can move though it.
Which material produce heat energy when electric current is passed though them and why?
Materials such as metals (e.g. copper, aluminum) and conductive materials (e.g. graphite) produce heat energy when electric current is passed through them because of resistance. Resistance is the property that causes the material to hinder the flow of electrons, converting electrical energy into heat energy. This phenomenon is known as Joule heating.
Can resistivity be negetive?
No, resistivity cannot be negative. Resistivity is a material property that indicates how strongly a material opposes the flow of electric current. It is always a positive quantity, even though some materials may have very low resistivity values.
Is mica conductor?
Mica is not a conductor of electricity. It is actually an insulator, meaning it does not allow electricity to flow through it easily. Mica is often used in electrical and electronic applications as an insulating material to prevent current flow.
What material allows electrons move though it?
Electricity can flow through materials called conductors, such as metals like copper and silver. These materials have outer electrons that are not tightly bound to their atoms, allowing them to move freely and carry electric current.
What is the name giving to materials that allows electrical current to pass though them called?
Conductors.
What happens when a circuit is closed?
when a circuit is closed, electricity can move though it.
Why insulators are used in electronics though current cannot pass through them?
Because current cannot pass through them. They stop one part of a circuit from interfering with another.
What type of material allows a charge to move freely through it?
A material through which an electric current flows easily is called an electrical conductor. Many metals, especially silver and copper, are excellent electrical conductors.

What cause electrical shock volts or amps?
They both do. Voltage is a measure of electrical pressure. Amperage is a measure of electrical flow (current) (amount of electricity flowing). High voltage by itself will not kill you but will leave a nasty taste in your mouth. At the right pressure your heart can be stopped though by a single amp.
How would you send a current of electricity though sand?

Can resistivity be negetive?
No, resistivity cannot be negative. Resistivity is a material property that indicates how strongly a material opposes the flow of electric current. It is always a positive quantity, even though some materials may have very low resistivity values.
What type of electrical current is in most automobiles?
The typical automobile operates on DC (Direct Current) even though the typical alternator produces AC (Alternating Current) which is then converted to DC.
What are some examples of insulators and conductor?
As regards electrical conductors, these materials have free electrons that will support electric current flow. In general, all metals will conduct electricity, though some do it better than others. We know that silver, copper, gold and aluminum top the list of metals that have high electrical conductivity.Insulators don't have free electrons to support electric current flow. These materials include rubber, dry wood and dry paper, many plastics, glass, ceramics and many other materials.Boobaa
Where did AC DC come from?
In electrical terms AC means alternate current and DC means direct current. AC/DC comes from Australia (Perth and Sydney) even though most of them have Scottish heritage.
Will electricity run thru brass?
Yes, electricity can run through brass because it is a conductive alloy primarily made of copper and zinc. The presence of copper in brass allows it to conduct electrical current, though it is not as conductive as pure copper. Brass is often used in electrical applications where corrosion resistance is also a factor. However, for optimal conductivity, materials like copper or aluminum are typically preferred.
