Question

four wires made of same material have different lengths and radii , the wire having more resistance in the following case is ?

Answer 1

Hi friend here is your answer

##################

Since resistance is proportional to length and inversely proportional to area,

Therefore, resistance more will be in that wire whose lenth is more and area is small.

Since they are of same material, the resistivity will be neglected.

Answer 2

Heya, here is your Answer :-

Resistance depends upon 4 Characteristics :-

➡ Length (Resistance is Directly proportional to the Length of the wire.)
➡Area (Resistance is inversely proportional to the Area of the Cross - Section of the Wire.)
➡ Temperature(Resistance is directly proportional to the Temperature of the wire.)
➡ Material (Resistance depends upon the Material of the Wire.)

So,
The wire with longest length and shortest radii or longest length or shortest radii will be having more resistance...
