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.
In a transmitter the final stage class C amplified with 18V DC supply calculate what equivalent Road the transistor to an antenna with 50ohm load impedance design and draw an L n
A ray of light in air is occurrence upon a flat piece of glass. How acts the path that the light travels along when it is in the glass compare with the path in the air?
Light coupling: Another way to look at light guiding in a fibre is to measure the fibre's acceptance angle. This angle is the angle within which the light should enter the fib
The dimentional formula of pressure ML -1 T -2
A single-phase transformer has 2400 turns on the primary and 600 turns on the secondary. Its no-load current is 4A at a power factor of 0.25 lagging. Suppose the volt drop
Stretch the fingers and thumb of right hand at right angles to one another. Then if the fingers shows in the direction of field and thumb in the direction of current i, then normal
I want to know about renewal time, such as the Greenland Ice shelf melting. How much does it cost to have the equations and to have this explained please?
Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing
It describes that the total energy (pressure energy, potential energy and kinetic energy) of an incompressible and non-viscous fluid in steady flow by a pipe remains constant throu
1. Discuss the internal noise sources that are present in a typical signal source and amplifier circuit, and describe their effects. 2. The company currently has a low noise a
