Question

how resistance is related to the conductor , insulator and rheostat ?​

Answer 1

Answer:

We know that, resistance of a wire inversely proportional to a current carrying conductor.

If conductor is thick then current pass easily through thick conductor because resistance is less...

If we use thin wire then current do not pass easily because resistance is high....

Answer 2

Answer:

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.
