    Revered Members,
    I want the answer for the following question
    Joule Kelvin effect is to produce
    a) high temperature b) moderate temperature c) low temperature d) temperature below 0.4K
    I know Joule Kelvin effect is to produce low temperature by throttling process. So I guess,the answer should be either (c) or (d). But since specifically mentioned 0.4 K, i am confused.
    Revered members, I solicit your help in this regard.
    Thanks in advance.
