When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. The reason for this change in temperature is the transformation of some electric energy passing through the conductor into heat energy.
How is heating effect of electric current used in electric bulb?
Electric bulb works on the principle of heating effect of electric current. When electric current passes through a very thin, high resistance tungsten filament of an electric bulb, the filament becomes white hot and emits light.
What is heating effect of electric current class 10th?
When electric current is supplied to a purely resistive conductor, the energy of electric current is dissipated entirely in the form of heat and as a result, resistor gets heated. The heating of resistor because of dissipation of electrical energy is commonly known as Heating Effect of Electric Current.
What are the important applications of an electric bulb?
- Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity. …
- Electric iron: The element of electric iron is made of alloys having high melting point. …
- Electric fuse: Electric fuse is used to protect the electric appliances from high voltage; if any.
What are the two effect of electric current?
Answer: The two effects of electric current are; heating effect and magnetic effect.
What are the four effects of electricity?
Name four different effects of electric current?
- Magnetic effect.
- Chemical effect.
- Heating effect.
- Electric shocks.
What is the formula of heating effect?
Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating.
What is heat effect?
Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and death, as well as exacerbate preexisting chronic conditions, such as various respiratory, cerebral, and cardiovascular diseases.
What are the four applications of heating effect of electric current?
APPLICATIONS OF THE HEATING EFFECT OF CURRENT
Electrical Heating Appliances: The heating effect of current is utilised in the working of electrical heating appliances such as electric iron, electric kettle, electric toaster, electric oven, room heaters, water heaters (geysers), etc.
In which appliance heating effect of electric current is used?
Applications of the Heating Effect of Current
(1) The heating effect of electric current is utilised in the working of electrical heating appliances such as electric room heater, electric iron, electric kettle, electric toaster, electric oven, water heater (geyser), immersion rod, and soldering iron, etc.
Which Mark is necessary on electric appliances?
ISI mark is the mark necessary for appliance approval.
What are 3 effects of electric current?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
What is electric current and its effect?
So, when electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current. In fact, an electric current can be used to make magnets.
