Question

states three factor on which resistance of a wire depends .explain how does the resistance depend on the factor stated by ​

Answer 1

Explanation:

The resistance of a wire depends on the following four factors :

(i)  the material of the wire - Good conductors of electricity having higher concentration of free electrons such as metals, offer less resistance.

(ii)  the length of the wire - A longer wire offers more resistance (Resistance is proportional to length).

(iii)  the area of cross section of the wire - A thicker wire offers less resistance (Resistance is proportinal to 1/ area of cross section.

(iv)  the temperature of the wire - The resistance of the metallic wire increases with the increase in temperature

Answer 2

Answer:

the factors on which the resistance of a wire depends are

• length of a wire
• it's cross sectional area
• it's material
• and temperature
