Electricity (Part-2)

The Theory of Relativity was developed by Albert Einstein. It actually encompasses two main interrelated theories:

The component used as an amplifying device among the common electronic components is a transistor.

Transistors:
These are semiconductor devices that can control the flow of electric current. A small current or voltage applied to one terminal (the base or gate) can control a much larger current flowing between the other two terminals (the collector and emitter, or drain and source). This ability to control a larger current with a smaller one is the essence of amplification. Transistors are the fundamental building blocks of most modern electronic amplifiers.

The physical quantity measured in Siemens (S) is electrical conductance.
Electrical conductance (G) is a measure of how easily an electric current flows through a material or an electrical circuit. It is the reciprocal of electrical resistance (R), which is measured in ohms ($\Omega$).

The physical quantity measured in the unit called Gauss (G) is magnetic flux density, also known as magnetic induction or the B-field.
The gauss is the unit of magnetic flux density in the centimetre-gram-second (CGS) system of units. The SI unit for magnetic flux density is the tesla (T). The conversion between gauss and tesla is:

1 T = 10,000 G

Atomic explosion is triggered by an uncontrolled chain reaction of nuclear fission (in the case of atomic bombs) or a combination of fission and fusion (in the case of hydrogen bombs).

1. Nuclear Fission: Heavy atomic nuclei (like Uranium-235 or Plutonium-239) are bombarded with neutrons, causing them to split into smaller nuclei, releasing a tremendous amount of energy and more neutrons.
2. Chain Reaction: The neutrons released from the initial fission go on to strike other nearby fissile nuclei, causing them to fission as well, releasing even more energy and neutrons. This creates a self-sustaining chain reaction.
3. Uncontrolled Reaction: In an atomic bomb, this chain reaction is allowed to proceed unchecked and rapidly multiplies, leading to a massive and sudden release of energy – the atomic explosion.

In essence, it's the rapid and exponential increase in the number of fission events, driven by the continuous release and absorption of neutrons, that triggers an atomic explosion.
