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.
Alex is on the wrestling team and has a mass of 85.3 kg. Being a whiz at physics, he realizes that he is over the 830.0-N cut off for his weight class. If he can convince the train
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
The lagging of an effect behind its cause; especially the phenomenon in which the magnetic induction of a ferromagnetic material lags behind the changing magnetic field.
Q. A capacitor blocks d.c. but allows a.c. Why? Capacitive reactance XC = 1/ω C = 1 / 2πν C Where ν is the frequency of the a.c. supply. In a d.c. circuit
