Firstly electricity is the flow of electrons.
An electric current moves in the opposite direction to that of the electrons themselves (unless i think you live in Canada... at any rate one country changed it) and as such is thought of as the 'positive' flow of electrons. So although electrons move from the negative to the positive terminal of a circuit, the current flows from the positive to the negative.
basic formula for looking at circuits:
V=I*R
V= voltage (in volts, the amount of energy that each coulomb has (Joules/coulomb))
I= current (in Amperes, basically speed of electricity(Coulombs/second))
R= resistance (in ohms, the amount of J*s/C^2, or total energy divided by coulombs squared) Electrons are orbiting charge particles around the nucleus and the number differs as shown in the Periodic Table. However if a potential is applied they leave said orbit and flow to the next nucleus leaving a hole behind. therefore as the electrons flow from positive to a more negative potential these HOLES flow in the opposite direction as a consequence. In the USA it is acceptable as electron flow. But the principle and result is the same if you understand it.
Electronics is not a small field the area of electronics is very vast and it can named several ways according to it's area.every field is called engineering. Electronics and communication is used for communicating and electronics devices Electronics and instrumentation is used for measurement and measuring tools development. But all are called engineering.

According up to my knowledge the electricity is the bracnch of physics which deals with the study of flow of current mostly throw pure conductor, while electronics is also the branch of physics but that deals with the mostly the study of flow of elcectrons throw semiconductor devices. In other words i want to explain the electicity is the basic thing which causes the electrictronic appliances to work on and electronics helps in controling and manintainces of electrical supplies. Electronics is aphysiucal study of electrons mmision. Electricity is the result of current flow.
electronics and telecommunication
Electrical-Electronics: 1.Electronics came out of electricals 2.Electricals: base & Electronics: Speciality Electronics-Instrumentation: Specialities based on Electrical Electronics i a part of physical study of electrons emission. Instrumentation is a fiels of specialty related to monitor,calibrate electronics components.
There is more Physics in Mechanical engineering as compared to Electronics engineering.
obviously physics
Yes, in electronics.
No. Electronics is a sub-set of physics.

physics and electronics
There is physics everywhere in a computer, but probably the most important individual part of physics is electricity and electronics.
Mechanics Thermodynamics Waves Electricity & Magnetism Electronics Nuclear Physics
Physics is a branch of science which studies the nature and properties of matter. Electrons are constituent parts of matter and so their study is a part of physics. The behaviour of electrons is governed by mathematical rules and that is why mathematics is critical for electronics.
Physics is used in the banking sector in various ways. The electronics used in the banking industry rely on physics and there is also the use of statistics which is part of physics as well.
First year physics includes mechanics and dynamics, energy, atomic theory, and a dustings of astronomy, electronics, and optics.
