Ohm's Law
Empirical physical law, defining the connection of the electromotive power of the source with the power of the current flowing in the conductor, and the resistance of the conductor.
Ohm's Law
What is Length?
The size of the object in the longitudinal direction (usually it is the direction of the largest size)
(1879-1955), theoretical physicist, one of the founders of the SOVR. Physics
Albert EINSTEIN
What is Atom?
The smallest particle of the chemical element, which is the bearer of its chemical properties.
Newton's first Law
If there are no external influences on the body, this body retains a state of rest or even rectilinear motion relative to the earth.
Resistance R
Depends both on the material on which the current is flowing, and on the geometric dimensions of the conductor.
Ohm's law in differential form
Numerical characteristic of two-dimensional (flat or cremated geometric figure)
Area
(1643-1727)-English physicist and mathematician, creator of theoretical Fundamentals of mechanics and astronomy.
NEWTON Isaac
What are Impurities?
Foreign atoms in pure material
Newton's second Law
The acceleration of the body is directly proportional to the body force and inversely proportional to the body mass.
If there is inductance or capacitance in the AC circuit, it is necessary to take into account their reactive resistance.
In this case, the record of Ohm's law will look like:
I = U/Z
Ohm's law for alternating current
Quantitative characteristic of the space occupied by the body or substance

What is Electron?
Quasi-particle in a solid body with an electron charge, but with an excellent mass.
Newton's Third Law
Let one body act on this body with the force of F1, then this body acts on the first body with force F2, equal to the modulus of force F1 and the opposite direction.
According to this diagram, the expression can be written formally:
R = U I, (7) R = U over I
Which only allows you to calculate (in relation to the known current, which creates a known voltage on a given section of the circuit), the resistance of this area. But the mathematically correct assertion that the conductor resistance grows directly proportional to the voltage applied to it and inversely proportional to the current flowing through it, is physically false.

What is Effective weight?
The adopted mass of the electron in the crystalline lattice.
Act of maintaining momentum
The vector sum of impulses of all bodies of the system is a constant value if the vector sum of external forces acting on the system of bodies is equal to zero
One of the most important requirements for power transmission lines is to reduce the loss of energy delivery to the consumer. These losses now lie in the heating of the wires, i.e. the transition of the current energy into the heat energy, for which the responsible OHSS resistance of the wires
Ohm's law and TRANSMISSION line
An arular physical value that determines the inertial and gravitational properties of solids in situations where their velocity is much less than the speed of light

What is Thermalization?
The process of establishing thermodynamic equilibrium for non-core charge carriers
The law of Mechanical Energy conservation
If all forces are conservative, there is a law of preservation of mechanical energy of interacting bodies: complete mechanical energy of closed system of bodies, between which only conservative forces operate, remains constant
