NUCLEAR CONSTITUENTS It is a known fact that from the scattering of α – particles, scientist Rutherford concluded that the atom of any element consists
Rectifier: A rectifier is a device that converts alternating current into direct current. Half wave rectifier: In this rectifier, the PN junction diode is connected
There are four major modes that the waves transmitted from a transmitter may follow to reach the destination and they are (a) Surface wave propagation
Let us derive the relation of electric field intensity at finite distance from transmitter Antenna If a horizontal Hertzian dipole antenna is used as a
Today we will discuss a very important relation related to wave propagation. The equation is known as Friis free space equation. As only a small
When a radio wave is radiated from the transmitting antenna, it spreads in all directions with decrease in amplitude with increasing distance because of spreading
In a PN junction diode holes are the majority carriers on P side whereas electrons are the majority carriers on n-side. The process of diffusion
