If you have two wires of the same material and length but different diameters, how does their resistance differ?

1

Wider wire will have higher resistance

2

Wider wire will have lower resistance

3

Resistance will be equal

4

Depends on the length of the wire

Answer and Solution

Answer

B. Wider wire will have lower resistance

Solution:

The thicker (wider) wire has a larger cross-sectional area, leading to lower resistance due to the reduced constraint on electron flow.
