How is the drift velocity in a conductor affected with the rise in temperature?

Text Solution

AI Generated Solution

To understand how the drift velocity in a conductor is affected by a rise in temperature, we can break down the explanation into several steps: ### Step 1: Understanding Drift Velocity Drift velocity (\(V_d\)) is the average velocity that charge carriers (like electrons) attain due to an electric field in a conductor. It is influenced by the electric field strength, the relaxation time (\(\tau\)), and the mass and charge of the electrons. ### Step 2: The Role of Temperature When the temperature of a conductor increases, the thermal energy of the atoms in the conductor also increases. This leads to increased vibrations of the atoms, which affects the motion of the electrons. ...
