1) The heating itself may be problematic in some cases. Electronic components (for example) may overheat, and it may require special equipment to carry the heat away fast enough.
2) The heat produced represents wasted energy.
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.
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.
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.
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.
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 .

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.

Heating Effect.
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 .
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.

The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).
