Question

State and explain Ohms law.On what factors does the resistance of a conductor depend?

Answer 1

Answer: Temperature and other physical parameters remaining constant current flowing through a conductor is directly proportional to the potential difference across it.

Explanation: Resistance is directly proportional to the length of the conductor and inversely proportional to the area of it.

Answer 2

$\sf \huge \underline{ \: Answer : \: }$

Ohm's law states that the current flows through the conductor is directly proportional to the potential difference of the battery

$\sf \mapsto V \propto I \\ \\ \sf \mapsto V = IR$

Where , R is the resistance of the conductor

The value of R is different for different materials

Factors on which resistance of the conductor depends :

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