Electricity is caused by electrons moving atom to atom. In electric current, atoms don't move, only the electrons, almost like a bucket brigade with no end.
The electron
electrons
That is called an electrical current, or just a current.
Heat Energy
The motion of electrons is called elecricity. Electricity is used to represent the liberated out put by the movement of electrons.
Mainly energy. Note that the electric current involves movement of electrons or other particles that are matter; however, the electric current "is" not so much the electrons (they exist whether there is a current or not; it is more precise that the current "is" the electrons' movement. Although even this may be an over-simplification.
These particles are the electrons.
electrons
Moving electrons or other charged carriers is called electricity. The amount of electrical pressure pushing the electrons is called the voltage. The number of electrons moving past some point in a given time is called the current. Electrons are subatomic particles (smaller than atoms) called leptons.
Electric current is defined as the movement of electrical charges.
Electrical current is all about charges in movement.
Electrical current is the measure of the flow of electrons, measured in Amperes (Amps). An example would be to compare it with a fluid flow meter. As opposed to pressure, which is analogous to Voltage.
To be precise, a current doesn't flow - a current "is". Although many people - including myself - often use the informal term "a current flows". The particles that make up the current do flow - or move. An electrical current involves the movement of some type of charged particles. Often, these are negative electrons, but there are other possibilities, as well, especially positive holes, and negative or positive ions.
A current usually involves the movement of charged particles. ANY charged particle will do; though quite often, it is the electron (negative charge). Other options include holes (positive), and ions (positive or negative) in a solution.
Electricity or Electric Energy is the energy formed by the motion of protons and electrons
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
Movement of electrical charges
Electrons are mostdirectlyrelated to electric current. (Electric current is caused by the movement of electrons between atoms.)
