What would happen to the resistance of a wire if it is stretched to double its length justify your answer?

When the wire is stretched to double the length , the area of cross section gets reduced to half. So when the wire is stretched, the resistance multiplies by four times.

How does increasing the length of a wire affect its resistance?

The resistance is directly proportional to the length of the wire, the longer the wire the greater the resistance. Well the longer the wire the more collisions the electrons will have with the atoms in the way from one end of the wire to the other. Therefore the resistance will increase as the length increases.

What happens to resistance when wire length increases?

When electrons start to move, they get scattered from the nuclei present in the material which is the wire made from. This process creates the resistance. Thus, when the length of the wire increases, the amount of particles scattered from the nuclei increases which also increases the resistance.

What happens when wire length increase?

The length of a wire when it is longer, causes the resistance to increase, when the wire is shortened the resistance decreases. A larger diameter wire will carry more current than a small diameter will. A longer wire will eventually carry less current, because the resistance increases as the length increases.

How the length of a resistance wire affected its resistance?

This is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow. Furthermore, the resistance of a wire is directly proportional to the length and inversely proportional to the area, so doubling the length of a wire should increase the resistance by a factor of two.

Does resistance change when wire is stretched?

Resistance of a wire is directly proportional to length and inversely proportional to cross sectional area . So whenever a wire is stretched its length increases and cross sectional area decrease . According to above proportionally the resistance of wire will increase .

How does the resistance of a wire change when its length?

The resistance of a wire is directly proportional to its length and inversely proportional to its area (or square of inverse of diameter).

How does resistance change with wire length?

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 relationship between resistance and wire length is proportional .
