A) 60
B) 50
C) 1.5
D) 0.67
Correct Answer: A
Solution :
For triode valve \[\mu ={{r}_{p}}\times {{g}_{m}}\] Given: \[{{r}_{p}}=30\,k\Omega =30\times {{10}^{3}}K\Omega ,\]\[gm=2\times {{10}^{-3}}\]mho Putting given values in eq (1) \[\therefore \]\[\mu =30\times {{10}^{3}}\times 2\times {{10}^{-3}}\] \[=60\]
