Why the temp of metallic wire rises when a current passes through it?
When current is passed through the wire, the negatively charged electrons (Current) face resistance as the molecules of the conductor block their way. These moving electrons collide with the molecules of the conductor and heat is produced which heats up the metallic wire.
Does every conductor heat up when electric current is passed through it?
yes every conductor heat up fast
How was current produce or induced?
Current is induced and not produced. when an electric wire is passed through magnetic field the current is induced in the electric wire, this electric wire is enamelled copper conductor of a rotor.AnswerCurrent is never 'induced' into a conductor. It is a voltage that is induced. If that conductor is then part of a complete circuit, then the induced voltage will cause a current to flow. The induced voltage will occur even when the conductor is open circuited.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
Why does conductor heat up when current is passed through after a long time?
Heating up means increase in average speed of atoms oscillation. When current passes through the conductor electrons collide (impact) with atoms and transfer a part of their energy to them increasing their average speed. Error: "average" instead of "average"
What does a conductor do in a magnetic field when current is suddenly passed through it?
the conductor has to be moved.
Will magnetic field is produced when current is passed through a thick conducting sheet?
Yes,,,a current carrying conductor wil produce magnetic field around it.

What is formed around a conductor when a current is passed through it?
A magnetic field.
Does every conductor heat up when electric current is passed through it?
yes every conductor heat up fast
When electric current is passed through water which gas is produced on cathode?
When an electric current is passed through water oxygen gas is produced on cathode because oxygen is positive and cathode is negative . So, oxygen is produced.
What shape is the magnetic field produced when current is passed through wire?
CIRCULAR
What is lighting effect of current?
When electric current is passed through a conductor ,it becomes very hot and emits light. This is called the lighting effect of current.

Is aluminium magnetic when a current is passed throu it?
When current flows through any conductor, there is a magnetic field around the conductor. It doesn't matter what substance comprises the conductor. I guess that means that aluminum wire can be an electromagnet, but not a permanent one.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced
