What kills you when you get an electric shock?
electric current through your nerves and/or muscles, especially through your heart
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
What happends when an electric current passed through a piezoelectric crystals?
They physically change shape.
What is observed when electric current is passed through copper sulphate?
its colour changes 2 blue
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.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
Simple definition of electronic signal?
The simple definition of an electronic signal is a mode of communication that is generated through electric means. This refers to an electric current that is passed in an electromagnetic field.
What will happen if you place a magnetic compass in an electric curcuit?
The compass will align itself with the magnetic field generated by the current flow through the wires.
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
What is hydroelecricity?
HydroelecTricity?power generated by water.usually held back by a dam, water is released through impellers, turning turbines on generators, creating electric current.
Why is heat generated across a resister when electric field is applied?
An electric current contains energy; so does an electric field. When a current flows through a resistor, part of the electrical energy will be wasted - i.e., converted to heat. You can think of this as if some of the electrons crash into atoms, instead of continuing on their way.
The flow of electrons through a conductor is called?
electric current
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
What are electromagents?
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
Why steel becomes a permanent magnet after electric current is passed through it?
Electric current is magnetic so when electric current pass through steel , steel will have the electric power and may be magnetic for awhile
