A) \[1:2\]
B) \[2:1\]
C) \[1:2\sqrt{2}\]
D) \[2\sqrt{2}:1\]
Correct Answer: D
Solution :
Thermionic current \[{{I}_{P}}\propto {{V}_{P}}^{3/2}\] \[\frac{{{I}_{{{P}_{1}}}}}{{{I}_{{{P}_{2}}}}}={{\left( \frac{400}{200} \right)}^{1/2}}=\frac{{{2}^{3/2}}}{1}=\frac{2\sqrt{2}}{1}=2\sqrt{2}:1\]You need to login to perform this action.
