Question

two copper wires are of same length one of them is twice as thick as 0/1 the other.then the resistance of two wires is in ratio
​

Answer 1

Answer:

1.thinner wire will have more resistance . R |/a area of cross - section.

2. thicker wire will have more specific resistance . Since specific resistance is directly proportional to length.

R= Si/ a

Ra=Si

S= Ra/l
