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.
When current is passed by a junction of two dissimilar solids, the temperature is either evolved or absorbed at the node. This effect is known as Peltier effect
ohm; Omega; O (after G. Ohm, 1787-1854): The derived SI unit of electric resistance, described as the resistance among two points on a conductor while a constant potential dif
D=(a÷Sqrt(h**k**l**))
Forward Characteristic of Zener diode Connect the circuit demonstrated in fig (a) using the 5.1 V zener diode. For forward characteristic, reverse the connection of zener di
In 1993, Ileana Salvador of Italy walked 3.0 km in under 12.0 min. Suppose that during 115 m of her walk Slavador is observed to steadily increase her speed from 4.20 m/s to 5.00 m
Define: Electric potential. The electric potential in an electric field at a point is define as the amount of work done in moving a unit positive charge from infinity to that
Question: The external surface of a short vertical segment of plastic pipe is hidden from view by wire wrapped around the pipe. Current flows clockwise as out looked from above
Q Give the differences between AF choke and RF choke. Audio - frequency (A.F) chokes Radio frequency (R. F) chokes: or high frequency (H.F) chokes
Q. What is a neutral buoyancy? Answer:- Buoyancy is the net upward force knowledgeable by an object submersed in a fluid. Pascal's principle utters that fluid pressure on
(a) Show that the total power in a 3-phase, 3-wire system using the two-wattmeter process of measurement is given by the sum of the wattmeter readings. Illustrate a connection diag
