When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor.
What are advantages and disadvantages of heating effect of electric current?
Disadvantages of the Heating effect of current:
Wastage of energy during power transmission in overhead cables is a major disadvantage of the heating effect. To counter the ohmic losses, electricity is transmitted in a high voltage. 2. The heating effect reduces the life of several components in a circuit.
What are the advantages of heating effect of current Brainly?
Almost whole the devices at homes, businesses and industries are running because of electricity.In simple terms the advantage of heating effect of current is heaters like water heater , room heaters etc; but in electrical system , heating effect of current increases the resistance thus resulting in increase in voltage …
What are the advantages of the heating effect?
In some situations the heating effect is an advantage, by using materials with high resistances and applying a large enough potential difference to produce a current it is possible to make the material heat up. This is used in conventional filament light bulbs and in electric heaters and cookers.
What is heating effect of current?
When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called heating effect of Electric Current. … This is because of heating effect of electric current.
What are the disadvantages of heat energy?
Disadvantages of Thermal energy
- It is considerably polluted by the continuous emissions of greenhouse gases.
- The vapor and heat emissions generated in the thermal plants negatively affect the climate of the place where they are located.
- The water used during the process ends up contaminated.
What are the disadvantages of the heating effect of current?
What Are The Disadvantages Of Heating Effect Of Current?
- When an electric current flows through the conductor, a part of it is converted into heat energy. …
- The heat produced can damage the insulation and other electrical components, or even cause a fire.
- Reduces the life of several components in the circuit.
What is electric current by Brainly?
An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles.
What is the disadvantages of electricity?
One of the biggest issues with electricity relates to how it is generated. Most of our current electricity requirements are fulfilled by fossil fuel based plants, more commonly known as thermal power plants. These generate greenhouse gases, apart from other wastes.
What are the disadvantages of heating effect of current Brainly?
Answer: The following are the disadvantages of heating effect of electrical current : The heat produced damages the insulation of connecting wires. Various electrical components can get damaged. Fires can be caused if inflammable objects are present nearby.
How can heating be reduced in wires?
How do we reduce the current and still transmit the same power? Simply increase the voltage. Remember, Power = Voltage x Current. If we increase the voltage by 10 times, we reduce the current by 10 times, and this reduces the power lost in the wire by 100 times.
