Question

5. On what factors does resistance of a conductor depend?answer according to class 10th ​

Answer 1

Answer:

hello guy!!!!!!!!!!!!!!!!!!!!!!

The resistance of a conductor depends upon the resistivity, length and cross-sectional area of the conductor which is given by the relation (R=ρl/a   ). It does also depend on other physical factors like temperature etc. Its SI unit is Ohm (Ω).

hope this will help you!!!!!!!!!!!!!!!!!

please mark as the brainlist

Explanation:

Answer 2

Answer:

Resistance is the opposition offered to the flow of current.

The resistance of a conductor depends upon the following factors such as :

• Length of the conductor
• Area of cross section
• Nature of the material

According to ohm's law, R=V/I.

where, R is the resistance of conductor, V is the potential difference across and I is the current supplied.

The S.I unit of Resistance is ohm.
