Question

state ohm's law. how does resistance depend on the temperature of a conductor ​

Answer 1

Answer:

$\huge{ \underline{ \mathtt{ \red{ ☆A} \pink{N} \green{S} \blue{W} \purple{E} \orange{R}}}}$

Explanation:

OHM's law states that under no same temperature, electric current flowing through an ideal conductor is directly proportional to the potential difference across its ends. V ∝ I.

Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, the resistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "slow" the flow of current.

thanks for asking;)

Answer 2

$\huge{ \underline{ \overline{ \mid{ \cal{ \red{ AnSwEr}}}}}}{ \mid}$

A law stating that electric current is proportional to voltage and inversely proportional to resistance is called ohms law.

Temperature resistance of wire is directly proportional to length and temperature and inversely proportional to cross section area.
