The current strength is a scalar quantity equal to the electric charge, which over a single time interval is transferred through some area of ​​the conductor section:
An electric current is called a constant, the force and direction of which remain unchanged over time.
Ohm's law for an arbitrary part of the circuit: the voltage (voltage drop) in the circuit section is equal to the product of the resistance of this section to the current strength.
The rule of contours (Kirchhoff's second rule): in any closed loop arbitrarily chosen in a branched electrical circuit, the algebraic sum of the products of the current forces by the resistances of the corresponding sections of this circuit is equal to the algebraic sum of the emfs existing in the contour:
The rule of nodes (Kirchhoff's first rule): the algebraic sum of the currents of currents converging at a node is zero:
Electrolytes are substances in which the electric current is carried out by ionic conductivity.
Ionic conductivity is the ordered motion of ions under the action of an external electric field.
Ions are atoms or molecules that have lost or attached to themselves one or more electrons. Positive ions are otherwise called cations, negative ions are called anions. A positively charged electrode is called an anode, a negatively charged cathode.
The first law of electrolysis (the first Faraday law): the mass of matter released at the electrode is directly proportional to the electric charge passed through the electrolyte:
The second law of electrolysis (the second law of Faraday): the electrochemical equivalents of substances are directly proportional to the ratio of their atomic (molar) masses to valence:
An electric current in gases is called a gas discharge.
Shock ionization (ionization by electron or ion impact) is the separation of one or several electrons from the atom (molecule) of a gas, caused by the collision with atoms (or molecules) of a gas of electrons or ions accelerated by an electric field in the discharge.
