Current flowing through any conductor encounters resistance in that conductor. This resistance produces heat. (Think of tires on a car after driving on the highway. Smooth trip, but a small amount of friction (resistance) is inevitable.

The heating effect of current refers to the phenomenon where the flow of electric current through a conductor leads to the production of heat. This occurs due to the resistance offered by the conductor to the flow of electrons. The amount of heat produced is directly proportional to the square of the current and the resistance of the conductor.

Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
State the situations where heating effect of electric current is undesirable?
negative effect of science .. with picture
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.
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 .
How do you derive joule's law?
State and derive joul's law of heating effect of an electric current.

Are resistor heating affected by line frequency?
No. The heating effect is the product of the square of the current and resistance, where the current is a root-mean-square value.A.C. current is always expressed as a root-mean-square (r.m.s.) value, which is equivalent to a d.c. current which produces exactly the same heating effect. Root-mean-square values are affected by the shape of a waveform, but not by its frequency.

What effects of electric current is involved in the fuse breaking?
Heating Effect.
Does nichrome wire get red hot when current is passed through it?
Yes ,due to heating effect of current.
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
