Amplifier is a functioning by which the amplitude of variation of ac signal voltage / current/ power can be enhanced
(i) Principle and circuit diagram: The amplifying action of the triode is based on the fact that small change in grid voltage produces the similar change in the grid voltage as because of a large change in the plate voltage. A circuit for triode as an amplifier
(ii) Working: First of all the mutual characteristic curves of a triode to be used as an amplifier is plotted and the grid potential - Corresponding to the mid-point of straight portion of characteristic curve is noted.

Q. Illustrate what does hull speed mean? Answer:- Hull speed- It is the theoretical limit of a sail craft's speed. It is able to be approximated by the following formula
Example 1:How far in meters does light travel in one year? Solution: 299,792,458m x 31,557,600s =9.461 x 10 to the power of15 Question, while i understand the above, why can we
