How Does Resistance Vary With The Length Of A Wire?

How does resistance range with the size of a wire? – when you’ve gotten longer size of wire, the present has to journey extra distance, extra the space increased the variety of obstacles it faces via its path.

Therefore resistance will increase with the size. This will be merely defined as under. When you’ve gotten longer size of wire, the present has to journey extra distance, extra the space increased the variety of obstacles it faces via its path.

Therefore resistance will increase with the size. When cross sectional space will increase the area of the elctrons to journey will increase(merely defined).

Therefore much less quantity of obstacles for the present. Therefore when space will increase the resistance decreases.
