Question

A triode has a plate resistance of `10 k Omega` and amplification factor `24`. If the input signal voltage is `0.4 V(r.m.s)`, and the load resistance is `10 k` ohm, then, the output voltage is (r.m.s.) is
A. `4.8 V`
B. `9.6 V`
C. `12.0 V`
D. None of these

Answer 1

Correct Answer - A
Use `V_(0)=AV_(S)`
Now `A=(24xx10k)/(10k+10k)=(24xx10)/20=12`
Therefore, `V_(0)=12xx0.4=4.8` volt (r.m.s.)
