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

Which effect of electric current is utilised in the working of an electrical fuse?
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 .
What effect of current is utilised in bulb?
The effect of current utilised in a bulb is the conversion of electrical energy into light energy through the heating of the filament inside the bulb. This process is known as resistive heating, where the current passing through the filament encounters resistance, causing it to heat up and produce light.
How would you show the heating effect of a current?
how would you show the heating effect of a current?
State the situations where heating effect of electric current is undesirable?
Heating effect of electric current is undesirable in electronic devices where overheating can lead to damage or malfunction. It is also undesirable in electrical transmission lines where energy loss due to heating reduces efficiency. Additionally, in some industrial processes where precise temperature control is required, excess heating can be a problem.
What is an electrical properties?
If you are asking, 'What are the properties of an electric current?', then there arethree. They are (1) the magnetic effect, (2) the heating effect, and (3) thechemical effect. The unit of measurement of current, the ampere, is defined interms of the current's magnetic effect.If that's not your question, then this answer won't help you.WebRepcurrentVotenoRatingnoWeight
Who found heating effect of electric current?
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
Why does heating effect of electric current happen?
When an electric current flows through a conductor, the electrons collide with atoms in the material, transferring energy in the form of heat due to resistance. This resistance causes the material to heat up, a phenomenon known as Joule heating. The heating effect is a result of the conversion of electrical energy into thermal energy.
What is an electrical current and what causes it?
Electrical current is nothing but movement of electrons in case of metals. It causes heating and produces magnetic field.
What happens to the heating effect when the direction of current is reversed?
When the direction of current is reversed, the heating effect remains the same. The amount of heat generated is determined by the magnitude of the current and the resistance in the circuit, independent of the direction of the current flow.
What are the advantage and disadvantages of heating effect of current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
Why does the heating effect of an electric current depends on the electrical resistance of a conductor?
The power dissipated by a resistance 'R' carrying a current 'I' is [ I2R ]. The power is dissipated as heat, and you can see from [ I2R ] that for a given current, it's directly proportional to 'R'.
Heating effect of a 5 amp of AC compared to 5 amp of DC?
Electrical current alone has no heating effect. Current through a device, with a voltage across the device will have a heating effect. The equation for calculating it is power = voltage x current, where power is proportional to the heating effect If the AC supply is measured as an RMS voltage and an RMS current and the device is resistive, then the heating effect will be identical to the same values with a DC supply. RMS means the "average" voltage or current of an AC supply whereas the peak AC voltage refers to the highest voltage that is reached on each cycle. However, if the device is not just resistive but is inductive, the heating effect will be lower with an AC supply than with a DC supply. By inductive, we mean that the device has a coil or capacitor, for example, in the circuit. The reasons why are outside the scope of this answer but are explained in many electronics text books, or look up "power factor" on google
