Question

List the factors on which the resistance of a conductor depends and write an activity to verify .

pls ans fast ....
will surely mark as brainlist!!
pls pls pls!!!!!

Answer 1

Answer:

• resistance of the conductor mainly depends on length of the conductor and area of cross section..
• length is directly proportional to resistance of the conductor
• area of cross section is inversely proportional to conductor

Answer 2

Answer:

1. Resistance of a conductor depends on following factors
2. length of the conductor

• Resistance lies on the wire at a particular distance so if the length of the wire increases , resistance also increase.

1. area of the cross section of the conductor

• Let's take example of a gate if the area of the gate is less than less people can enter through it and if the area of the gate is large then more people can enter through it
• same process applied to the current if area is large the more current pass through it and resistance is less and if the area is less than less current flow through it and resistance will be greater.
• That's why. R= L/R

1. Nature of the conductor is also a factor
