Insulation or a lawsuit.
Just kidding (sort of).
A magnetic field forms around the wire, because magnetic field are formed any time electric charge moves.

What is the relationship between the size of the electric current passing through a length of wire and its heating effect?
The relationship is that as the current passing through the wire increases so does the heating effect in the wire. To see its effect just use the formula: W=I2R R is resistance in ohms I is current in amps W is the heat output in watts Hope this helps
What did alternating electrical current effect in the 1920?
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
How does resistance effect the flow of current in a wire?
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
What are the effects of an open circuit?
The effect of an open circuit is that no current will flow.
Which effect of current does the fuse wire in electric circuits utilize?
The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped.
Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
Does nichrome wire get red hot when current is passed through it?
Yes ,due to heating effect of current.
What is the heating effect of electrical current?
As the current flows through the wire it increases the kinetic energy by increasing the vibration of the metal atoms. i.e. it generates heat in the wire
What is the relationship between the size of the electric current passing through a length of wire and its heating effect?
The relationship is that as the current passing through the wire increases so does the heating effect in the wire. To see its effect just use the formula: W=I2R R is resistance in ohms I is current in amps W is the heat output in watts Hope this helps
If you wire up a circuit with very thin wire what effect might this have?
less current will flow as resistance is inversely proportional to area
What is the effect on current in a wire if both the voltage across it and its resistance are doubled?
it will cause a Short Circuit
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
What is made by passing an electric current through coils of wire?
An electro magnet is created when a current is passed through a coil of wire. This effect is the main operation of how an electrical solenoid operates.
What did alternating electrical current effect in the 1920?
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
What effect would thinner wire have in a circuit?
The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
Examples of heating effect of electric current?
-kettle -electric heater that's all i have! :)) When a current passes through a wire, the wire heats up. This is caused by the conversion of electrical energy into heat energy. /the heat produced depends on the resistance of the wire.
How does resistance effect the flow of current in a wire?
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
