The plate resistance of a triode in `3 xx 10^(3)` aloms and its muthal of the triode is
A
` 5 xx 10^(-5) `
B
` 4.5`
C
`45`
D
`(0.2 xx10^(3)`
Text Solution
Verified by Experts
The correct Answer is:
B
(b) KEY CONCEPTWe know that `mu= g_(m) xx r_(0)` where `nu= `amplification factor, `g_(m) = `mutual conductance `r_(0) = `plate resistance `:. Mu = 3 xx 10^(3) xx 1.5 xx 10^(-3) = 4.5`
