Answer» Heya!!
Here is your answer.
Q-
Ans:-The electric resistance of a material is the MEASURE of hindrance it creates to the flow of electric current.
Read the following points to understand it better.
✨The magnitude of the current produced depends on its resistance.
✨The lower the resistance, the greater is the current.
✨Materials like metals have a very low resistance.So they conduct electricity well and are called good conductors or simply, conductors.
✨ Materials like wood, plastics, runner and mica conduct almost no electricity.They are called BAD conductors or insulators.They have a very high resistance.
✨There is no material which has no resistance.But, there are many materials like coal which have very low resistance.
✨ Resistance does not only depend only on materials. It also depends on the thickness and length of the material used.
✨A thin WIRE has HIGHER resistance than a THICK wire and a long wire has a higher resistance than a short wire.
Q-
Ans:-We measure electrical resistance in OHMS.
Q-
Ans:- We measure the resistance of a material by an instrument called the ohmmeter.
