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.
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
Assume a car rolls down a 52.0-m-long inclined parking lot and is stopped by a fence. If it took the car 11.25 s to roll down the hill, what was the acceleration of the car bef
Suppose that the x rays are emitted from a focal spot isotropically. The photon flux is 3.28 x 10 6 photons mm -2 sec -1 at a distance of 0.75 m from the focal spot. What is the
What is electric flux? Write its S.I. units. Using Gauss's theorem, assume an expression for the electric field at a point because of a uniformly charged infinite plane sheet.
