On what factors does the resistance of a conductor depend ?

Text Solution

AI Generated Solution

To determine the factors on which the resistance of a conductor depends, we can analyze the relationship between resistance and various physical properties of the conductor. Here’s a step-by-step solution: ### Step 1: Understand the Concept of Resistance Resistance is a measure of how much a conductor opposes the flow of electric current. It is denoted by the symbol \( R \). ### Step 2: Identify the Factors Affecting Resistance The resistance of a conductor depends on three main factors: ...
