Question 1: What is the relationship between stored energy and total input power?

a) As the total input power increases, the stored energy decreases.
b) As the total input power increases, the stored energy increases.
c) There is no relationship between the two.
Answer 1

Question 2: What happens to the energy confinement time in low mode plasmas when the total input power is increased?

a) The energy confinement time increases. (that's good!)
b) The energy confinement time decreases. (that's bad!)
c) Nothing happens
