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.

What is the study of electronics called?
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.
Who is credited with coining the word electronics and when was it created?
* Times Magazine - 'the largest dollar order for electronic equipment' * M. McLuhan - 'the new electronic and organic age' * Physics Bulletin - ' the central part to be played by the electronics industry' * British Medical Journal - ' the launch of an electronic journal'

Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics[1][2] and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. see more
What is the relation between electricity and electronics?
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.

How does physics and mathematics connect to electronics?
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.
What courses or subjects of physics are considered a year of physics?
First year physics includes mechanics and dynamics, energy, atomic theory, and a dustings of astronomy, electronics, and optics.
