9) I) Explain why a conductor offers resistance to the flow of current.
ii) Differentiate between conductor, resistor and resistance.
Answers
Answer:
1)An electric current flows when electrons move through a conductor, such as a metal wire. ... This makes it more difficult for the current to flow, and causes resistance
2)A resistor is an electric component with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it.

Conductor : A substance which allow to pass the charges through them easily is called a conductor.
Resistor : A conductor having some value of resistance is called a resistor.
Resistance : It is the property of any conductor by virtue of which it opposes the flow of charge through it.
