Question

A long wire has ........... resistance than a short wire​

Answer 1

Answer:

A long wire has more resistance than a short wire.

Extra information:

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. ... The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current.

Answer 2

A long wire has more resistance than a short wire.

Explanation:

Resistance is defined as the limitation to the flow of current in an electric circuit.

The SI unit of resistance is ohm Ω

The resistance in a wire increases when  

1. The length of the wire increases
2. The thickness of the wire decreases

• As a result of freely moving electrons, the current is produced.

• These moving electrons sometimes collide with the ions in the metal.
• This limits the flow of current and causes resistance.
• A long wire has more resistance than a short wire because electrons collide with many ions as they travel through the wire.
• Therefore, the relationship between resistance and wire length is directly proportional.
