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.
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.
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.
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.
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.

What effects of electric current is involved in the fuse breaking?
Heating Effect.
Which effect of current is utilised in the working of an electric 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 .
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 causes heating effect when current flows?
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.
What are the three effects of electric current?
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).
