------------------------------------------------------------------------------------------------------
〰◻The Ability of a conductor to Resist the flow of charges within it termed as Resistance.. It depends on the following factors :-


✔Temperature

✔Length of Wire

✔Area Of Cross Section

◻〰THe Resistance is Directly proportional to the length i,e more the length more is the resistance.

〰◻The Resistance is Inversely proportional to the Area of Cross section .lesser area of Cross section means more resistance.

Answer 2

resistance simply means obstacle that come across flow of current.following are the factor which influence the flow of resistance.

1 ) LENGTH OF CONDUCTOR

➡ resistance is directly proportional to length of conductor.

➡ this means if the length of conductor is more then the resistance also will be more.

➡ if the length of conductor is Less then the resistance will be less.

2 ) AREA OF CROSS SECTION :

➡ RESISTANCE is inversely proportional to area of cross section.

➡ if the area of cross section of conductor is less than the resistance is more.

➡ if the area of cross section is more than the resistance is less .
