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.
The wire will heat up and melt if the current is excessive.
A current flowing through a wire will create a magnetic field around that wire.
Voltage, Ohms, and Amperes
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
The introduction of alternating electrical current, in 1920, eliminated the need for a return wire. Alternating current, AC, replaced direct current, DC.
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
The effect of an open circuit is that no current will flow.
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.
Joule showed the heating effect due to the resistence of wire which cary the current.
Yes ,due to heating effect of 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

less current will flow as resistance is inversely proportional to area
it will cause a Short Circuit
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.
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.

The smaller the wire size used in a circuit limits the amount of current that is allow to be flow through that circuit.
-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.
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
