An electron experiences two collisions in a metal at uniform temperature in a uniform E field. What can you say about this? |
After first collision, electron accelerates in time t due to E field. Resulting velocity after second collision is the same since the temperature is uniform. This does not mean no energy is lost. Direction is random. Can find average over all possible directions. |
