Question

use the drop - down menus to complete the sentences. a thin wire has resistance than a thick wire. a short wire has resistance than a long wire. a warm wire has resistance than a cool wire.

Explanation:

Step1: Consider cross - sectional area effect

Resistance is inversely proportional to cross - sectional area. A thin wire has smaller cross - sectional area, so more resistance.

Step2: Consider length effect

Resistance is directly proportional to length. A short wire has less length, so less resistance.

Step3: Consider temperature effect

For most conductors, resistance increases with temperature. A warm wire has higher temperature, so more resistance.

Answer:

  1. more
  2. less
  3. more
