Semiconductor Electronics Materials Devices And Simple Circuits Ques 95
95. For amplification by a triode, the signal to be amplified is given to
[1992]
(a) the cathode
(b) the grid
(c) the glass-envelope
(d) the anode
Show Answer
Answer:
Correct Answer: 95.(b)
Solution:
- (b) The amplifying action of a triode is based on the fact that a small change in grid voltage causes a large change in plate current. The AC input signal which is to be amplified is superimposed on the grid potential.
