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.
what difference between these two laws
A) Explain the flow of direct current? ( describe direct current) b) Explain the effect of resistance in circuits? (Describe effect of resistance)
CPH has mass and velocity. What is its De Broglie wavelength? Answer; since I told before, the wavelength of CPH is equal of electromagnetic wavelength when it is growing.
If a particle in periodic motion moves back and forth (or to and fro) over the same path, then its motion it is called as vibratory or oscillatory. The examples of vibratory or osc
