Answer these questions

Answer 1

Answer:

A material with high resistance require a high potential to generate a given amount of current in the material..

A material with low resistance require a low potential to generate the same amount of current..

Answer 2

2. The wires which allow electricity to flow very smoothly are said to have low resistance. (10ohms or less)

the wires which do not allow electricity to flow very smoothly are said to have high resistance.(200 ohms or greater)

3.

4. The resistivity of wire depends on 4 Factors

-Length

-Area of cross section

-Material.

-Temperature

5.

6. The longer the wire the more the resistance.

7. No it is not needed, infact resistivity opposes the flow of electron.

8. ohm- meter

9. Diamonds do not conduct electricity.
