alleryThe average time between electron collisions is called the:
ARefraction time
BRelaxation time
CRelative time
DReflection time
Answer & Solution
Correct answer: B. Relaxation time
1. Electrons are accelerated between collisions.
2. The average value of that time is known as the relaxation time.
3. So the correct answer is relaxation time.
