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.
define pseudo force and mathematical expression and explanation
Show the ray diagram showing the experimental arrangement for pure spectrum.
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
Physical principle of nuclear medicine imagining: Since the gamma camera obtain the image in less time, it is usually preferred over the rectilinear scanner Thyroid imagining
An object is thrown downward from a 150 cliff so that it makes an angle of 30 with the horizontal. (a) How fast will it be going when it hits the ground? (b) How long will it take
Defects of vision and their correction There is a simple relationship between the focal length F ,the object distance P and the image distance Q of a thin lens fig(1).
When water is boiled under a pressure of 2.00 atm, the heat of vaporization is 2.20 x 10^6 J/kg and the boling point is 120Degrees C. At this pressure, 1.00 kg of water has a volum
