Will a thicker or thinner copper wire of the same length allow more electric current to pass through?
A thicker wire will transmit more current
What is an electric current and why is it so important?
Electric current is electric charge in motion. Most electric charge is carried by the electrons and protons within an atom and is affected by conductivity of elements ie copper.
Will a copper or steel wire of the same length and thickness allow more current to pass through?
Copper is the better conductor. The only materials that are better conductors than copper are either very expensive (such as gold and silver), or superconductors that only work at cryogenic (supercold) temperatures.
What matter has the ability to carry an electric current?
An electrical conductor has the ability to carry an electric current. Most of the best conductors are metals such as copper. Water containing ions can also conduct an electric current (which lead-acid batteries rely on)
How is a simple electromagnet created?
By passing an electric current through any conductor, a magnetic field will be created. Therefore, a simple electromagnet can be created by connecting a power source to a coil of copper wire.
Does copper get heated when electric current is passed through?
yes it does
Why does more current flow through the bulb when the reed switch was replaced with copper wire?
Copper wire has apparently lower resistance than the reed switch. The lower electric resistance, the higher electric current.
What is observed when electric current is passed through copper sulphate?
its colour changes 2 blue
What material allows electric current to pass through?
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
Will a thicker or thinner copper wire of the same length allow more electric current to pass through?
A thicker wire will transmit more current
How does an electric circuit with a battery lamp copper wire and switch work?
The battery provides the current and the energy; the lamp consumes the energy when the current goes through it; the copper wire conducts the current; and the switch lets you close or open the circuit (so that current passes, or doesn't pass, through).
Electric current in a copper wire is normally composed of what?
Electron current in a copper wire is normally composed of electrons.
Why electrical wires have plastic covering?
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
How do you use electromagnet in a sentence?
Electromagnetism occurs when an electric current is sent through a coil of copper wire that is wrapped round an iron core.
Materials that allow the charges of an electric current to move freely through them are called what?
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
Does copper wire carry electric current?
It is a conductor & common in wiring.
