Does the electric current have other effects also?
Answer: Yes, electric current have other effect except heating, i.e. magnetic effect of current. When electric current is passed through a coil, there is a magnetic field developed around the coil or wire, if magnetic compass is placed near by, it deflects the magnetic needle.
What are the effects of electricity?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect. Note:we have discussed briefly about the effects of current. You need to memorize the effects namely heating effect, magnetic effect and chemical effect.
What are the four effects of electricity?
The main effects are heating, chemical and magnetic effects. When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.
What are the two effects of electricity?
Answer: The two effects of electric current are; heating effect and magnetic effect.
Why should we not touch the lighted bulb?
Answer: we Should not Touch The Lighted Bulb As Due to Flow Of Current The Bulb get heated While Touching It can harm Or Damage That Person..
What is electric current and its effects?
He concluded that electric current produces a magnetic field around the wire. … Electric bell works based on the principle of magnetic effect of electricity. Electromagnet. Wrap a wire around a soft iron piece (known as the core). When an electric current is passed through the wire, the iron piece behaves like a magnet.
What are the negative effects of electricity?

- Varying Impacts. …
- Greenhouse Gases. …
- Pollution and Acid Rain. …
- Waste Disposal Challenges. …
- Injuries to Wildlife.
What is a disadvantage of electricity?
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. … Another issue of electricity is the risk of accidents, in terms of short-circuiting, electric shocks, fire hazards, etc.
What happens if we use too much electricity?
Our over-use of electricity is a big problem. It contributes to global warming, which is something that we really should be worried about. It is harming our environment and we need to do what we can to stop it. Not only that, but if we continue to use the same large amount of energy we will soon run out.
Is electricity harmful to your health?
According to WHO , extremely low frequency and radiofrequency EMFs are unlikely to cause any adverse health effects. You should feel safe using your cell phone and appliances. Power lines are also considered safe, as long as you keep a safe distance from them.
What are the effects of electricity Class 7?
Electric current has the following effect : (i) Electric current can give rise to heating and lighting. (ii) Electric current can convert a straight conductor into a temporary magnet.
What is called magnetic effect of electric current?
It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect. This phenomenon is called electromagnetism.
What is heating effect of current electricity?
When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called heating effect of current.
