Question

Two copper wires A and B of length 30 mand 10 m have rada 2 cm 1 cm respectively Compare the
resistances of two wires. Which wire will have less resistance?​

Answer 1

Answer:

wire A will have more resistance as resistance increases with increase in Length

Answer 2

Answer:

the resistance depends on length and area

resistance is directly proportional to length and inversely proportional to area

find the area using radius value with formula pi r2
