drwls said this is wrong but i don't know what's correct

the enregy gained by electrons as they are accelerated by an electric field is
a. greater than the average loss in energy due to collissions
b. equal to the avergae loss in energy due to collissions
c. less than the average loss in energy due to collissions
d. not affected by the gain in energy due to collissions

i get D
Answered by Damon
If the electron continues to be accelerated then it must be gaining more energy from work done by the field than it is losing by collisions along the way.
Answered by physics
then it's A?
Answered by drwls
In my previous answer, I assumed a steady state situation such as exists in a gas discharge where the energy gained by electrons between collisions equals the average energy lost in inelastic collisions.

Damon is describing a different unsteady situation.
