For a vacuum triode, the values of E(c),...

For a vacuum triode, the values of `E_(c)`, `E_(b)` and `l_(b)` are given as under

The values of `mu` and `r_(p)` are given by

A

`mu=12,r_(p)=10kOmega`

B

`mu=12, r_(p)=20kOmega`

C

`mu=10,r_(p)=20kOmega`

D

`mu =20,r_(p)=10kOmega`

Text Solution

Verified by Experts

The correct Answer is:
D

`mu = ((DeltaV_(b))/(DeltaV_(g)))_(l_(b))=((DeltaV_(b))/(DeltaV_(c)))_(l_(b))` ("Max". `DeltaV_(p))`
`(200-100)/5 = 20`
`r_(p) = ((DeltaV_(p))/(Deltal_(p)))_(V_(g))` ("Min".`DeltaV_(p)) = (140-100)/(9-5) = 40/4 = 10kOmega`
