DAY 3 QUIZ

What happens to the resistance of a conductor when temperature increases?

• Increases

• Decreases

• Remains the same

• Doubles

Which type of material generally shows a decrease in resistance with increasing temperature?

• Metals

• Insulators

• Semiconductors

• Superconductors

How does increasing temperature affect the movement of free electrons in a metal conductor?

• Electrons move faster, decreasing resistance

• Electrons collide more, increasing resistance

• Electrons stop moving, making resistance infinite

• Electrons move in a straight path

Which material is most affected by temperature changes in terms of resistance?

• Conductors

• Insulators

• Semiconductors

• Superconductors

A copper wire is heated from 20°C to 80°C. What happens to its resistance?

• It decreases

• It remains constant

• It increases

• It becomes zero

In most metals, resistance decreases as temperature increases.

• TRUE

• FALSE

he resistance of an ideal conductor remains the same regardless of temperature changes.

• TRUE

• FALSE

As the temperature of a metallic conductor increases, the number of free electrons also increases, reducing resistance.

• TRUE

• FALSE

When a metallic conductor is heated, the atoms vibrate more, making it harder for electrons to flow, thus increasing resistance.

• TRUE

• FALSE

The resistance of a metallic conductor remains constant regardless of temperature changes.

• TRUE

• FALSE
