A triode has `r_(p)=10Omega` and `mu=20`. Table gives the operating point with blanks.

The values of `E_(b1)` and `E_(c1)` are

A

290 V, `-6V`

B

210 V, `-10V`

C

290 V, `-10V`

D

210 V, `-6V`

Text Solution

Verified by Experts

The correct Answer is:
D
`r_(p) = ((DeltaV_(p))/(Deltal_(b)))`
`10kOmega = (250-E_(b_(1)))/(4mA)`
`10 xx 4 = 250 - E_(b_(1))`
`E_(b_(1)) = 210 V
`mu = (DeltaV_(p))/(DeltaV_(g)) = (40)/(E_(c1) + 8)`
`8 + E_(c_(1)) = 40/20`
`8-2=-E_(c_(1))`
`E_(c_(1)) = -6V`
