I am to find the mean time between collisions of electrons in a wire and am having a difficult time manipulating equations with known variables. I am given values for E, J, n and rowe.
v = (qT/m)*E
rowe = E/J
J = nqv
The Attempt at a Solution
I have tried every possible combination of ways to manipulate this equation but I guess my problem is q. I don't think I know the value or can assume it and I can't cancel it out anywhere!
