Factors Affecting Electric Resistance Quiz

What is the relationship between the material of the conductor and its resistance?

• The material of the conductor has no effect on its resistance

• All conductors have the same resistance regardless of their material

• Resistance is only affected by the length and thickness of the conductor, not the material

• Different materials have different resistivities, which directly affect the resistance of the conductor.

How does the resistivity of a material affect its resistance?

• It has no effect on the resistance of the material.

• It increases the resistance of the material.

• It decreases the resistance of the material.

• It changes the color of the material.

How does the length of a conductor affect its resistance?

• The resistance increases with the length of the conductor.

• The resistance remains constant regardless of the length of the conductor.

• The length of the conductor has no effect on its resistance.

• The resistance decreases with the length of the conductor.

What is the formula to calculate the resistance of a conductor based on its length?

• R = ρ / (L*A)

• R = ρ * (A/L)

• R = L * A

• R = ρ * (L/A)

How does increasing the cross-sectional area of a conductor affect its resistance?

• It increases

• It has no effect

• It causes the resistance to fluctuate

• It decreases

What is the formula to calculate the resistance of a conductor based on its cross-sectional area?

• R = ρ * (L/A)

• R = A/L

• R = L/A

• R = V/I

How does decreasing the temperature of a conductor affect its resistance?

• The resistance of a conductor increases

• The resistance of a conductor stays the same

• The resistance of a conductor decreases

• The resistance of a conductor becomes negative

What is the relationship between temperature and resistance in conductors?

• Intermittent relationship

• No relationship

• Directly proportional

• Inverse proportional

How does the type of circuit affect the resistance of a conductor?

• It has no effect on the resistance

• It affects the resistance by determining the flow of current and the arrangement of the components in the circuit.

• It increases the resistance by decreasing the flow of current

• It decreases the resistance by increasing the flow of current

What are the differences in resistance between series and parallel circuits?

• The total resistance in parallel circuits is the sum of individual resistances.

• In series circuits, the total resistance is less than the smallest individual resistance.

• The resistance in series circuits is less than the resistance in parallel circuits.

• The total resistance in a series circuit is the sum of individual resistances, while in a parallel circuit, the total resistance is less than the smallest individual resistance.
