Question

Which statement best describes resistance? Resistance is



how well a current will flow in a material and is measured in volts.

how well a material conducts an electrical charge and is measured in ohms.

the ability of a material to attract a positive charge to create a current.

the ability of a material to repel neutral charges and is measured in ohms.

Answer 1

Resistance is how well a material conducts an electrical charge and is measured in ohms.

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

Resistance is defined as the ability of a substance to resist the slow of electrons or charges through it.

This means that a resistance is the measure to see how difficultly a charge is flowing through a material. Resistance is represented by R and it's S.I unit is ohms.

According to ohms law, electric current is proportional to voltage and inversely proportional to resistance.

Mathematically,     V = IR

where,    V = voltage

               I = current

               R = resistance

Thus, we can conclude that the statement ability of a material to repel neutral charges and is measured in ohms, best describes resistance.
