Question

If all other things remain equal, which of the following changes to a closed circuit

would result in increased resistance to the flow of electric current?
Reducing the temperature of the conductor
Reducing the thickness of the conductor
Replacing the conductor with a more conductive material
Reducing the length of the conductor

Answer 1

Reducing the thickness of the conductor

Step-by-step explanation:

Answer 2

the answer is b reducing the thickness of the conductor

Step-by-step explanation:

The resistance to electric current increases as the cross-section of the conductor is reduced, as the conductor is lengthened, and as the conductor is heated. Replacing the conductor with a less-conductive material increases the resistance as well.
