The temperature of a wire increases when current flows through it due to resistance. As the electrons move through the wire, they collide with the atoms in the wire, causing them to vibrate and generate heat. This phenomenon is known as Joule heating.

Why does the resistance of a filament depend on the current?
The resistance of a filament depends on the current flowing through it because as current flows through the filament, it heats up due to the electrical energy converting into heat energy. This increase in temperature causes the resistance of the filament to increase, resulting in a higher overall resistance in the circuit.
What happens to the temperature of the filament as the bulb becomes brighter and brighter?
As the bulb becomes brighter, more current flows through the filament, increasing its temperature. This increase in temperature causes the filament to glow more intensely, resulting in a brighter light output.
Resistor get hot when electrical charge flows through it?
When an electrical charge flows through a resistor, some of the electrical energy is converted into heat due to the resistance of the material. This heat causes the resistor to get hot, and the temperature increase is proportional to the amount of current flowing through it and the resistance of the resistor. If too much heat is generated, the resistor may be damaged or experience a change in resistance.
What type of energy flows through a wire?
Electric energy flows through a wire when an electric current passes through it.
State three factors on which the heat produced by an electric current depends?
The heat produced by an electric current depends on the resistance of the material through which the current is passing, the square of the current flowing through the material, and the duration for which the current flows.
When electric currnet flows through a conductor then temperature of conductor will?
increase
What happens to a nichrome wire when a current flows through it?
When a current flows through a nichrome wire, the wire heats up due to resistance. This increase in temperature causes the wire to glow and emit heat, which is why nichrome wire is often used in heating elements and appliances.

Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
Does resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
What flows through a complete circuit?
Current flows through a complete circuit.
When a electric current flows through a wire it creates a?
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
How does a current flow through a wire?
according to kcl the current flows through a wire

This heat causes the resistor to get hot, and the temperature increase is proportional to the amount of current flowing through it and the resistance of the resistor. If too much heat is generated, the resistor may be damaged or experience a change in resistance.
