Question

define:
1.Heating effect of electric current
2.Element
3. Electric fuse
4.Magnetic effect of electric current
5.Electromagnet
​

Answer 1

1)When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. This happens due to the conversion of some amount of electricenergy, passing through the conductor, into heat energy. This effect of electric current is called heating effect of electric current.
2)In chemistry and physics, an element is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. ... The number of protons in the nucleus of the atom of an element is known as the atomic number of that element.
3) a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current.
4)The magnetic effect of electric current is known as electromagnetic effect. 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 currentproduces a magnetic effect.
5)An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of wire wound into a coil.

Answer 2

1) Heating effect of electric current :- Electric current is passed through a conductor, the conductor become hot after some time and produce heat.. This is called Heating effect of electric current.

2) Element :- A substance that cannot be broken down into simpler substances....

3) Electric Fuse :- It is a safety devise that can stop current from flowing if it overloaded...

4) Magnetic effect of electric current :- It is also called electromagnet. It observe that when a compass is brought near to the current carrying conductor the needle of deflected because of the flow of electricity.

5) Electromagnet :- An electromagnet is a magnet in which the magnetic field is produced by an electric current.

I hope this will help u..
