A) \[25\,\,V\]
B) \[15\,\,V\]
C) \[12\,\,V\]
D) \[10\,\,V\]
Correct Answer: B
Solution :
The grid potential required to make plate current zero is given by \[{{V}_{g}}=\frac{{{V}_{p}}}{\mu }\] Given, \[{{V}_{p}}=300\,\,V,\,\,\mu =20\] \[\therefore \] \[{{V}_{g}}=\frac{300}{20}=15\,\,V\]You need to login to perform this action.
