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.
derive an expression for the variation of g with altitude or depth

(1) Directive properties: When a magnet suspended freely it remains in the earth's N-S direction (in magnetic meridian). (2) Monopole concept: If a magnet is broken into number
A lift is moving down with an acceleration of 3m/s. A ball is released 1.7m above the lift floor. How long will the ball take to hit the floor?
Elastic Collision Collisions among objects are governed through laws of momentum and energy. While a collision occurs in an isolated system, the whole momentum of the system of
