Question

on what factors does the resistance of a conductor depend? give its expression with units​

Answer 1

Explanation:

Hope this helps you with your question :-))

Answer 2

Answer:

SO IT'S GIVEN IN NCERT TEXTBOOK AS WELL, I WILL USE '~' AS SIGN OF PROPORTIONALITY

R ~ LENGTH OF CONDUCTOR (L)

R ~ AREA^-1 OF CONDUCTOR OR

R IS INVERSELY PROPORTIONAL TO AREA OF THE CONDUCTOR.

FURTHER

R= pL/A "p" (read as rho) is a constant called resistivity.

Explanation:

So first know what causes resistance?

what is resistance?

and then just read your text book you will know why resistance of current is proportional to lenght and inversely to area. MAKE SURE YOU UNDERSTAND RESISTIVITY
