Ohm's law - calculator
Knowing only two data, it is possible to trace all the others affected by Ohm's law (voltage, current intensity, resistance and power).
The results are shown in direct, alternating and three-phase alternating current.
In addition to the Ohm triangle, the characteristic values of cos φ are indicated
Ohm's law is a mathematical formula that describes the correlation of electrical quantities (resistance, current, voltage) as they vary.
By resistance (R) we mean the obstacle that the current encounters in its path, the higher it is, the more difficult it will be for the current to cross it; its unit of measure in the SI (international system) is the ohm, represented by the Greek letter omega (Ω).
By current (I), expressed in amperes, we mean the quantity of electrical charges that pass through a conductor in the unit of time.
By voltage (V) instead we mean the potential difference of one point with respect to another expressed in volts.
Clearly, the higher the obstacle, the lower the intensity of current that passes through it, it is therefore clear that, with the same ddp (potential difference) applied, the current is inversely proportional to the resistance.
For the voltage, on the other hand, the higher it is, the greater its attraction force which it generates to move the electric charges, consequently for the same resistive value it will be directly proportional to the current intensity.
The name is due to the German physicist Georg Ohm, who, in a treatise published in 1827, described the measurement of current and potential difference through simple circuits with wires of different lengths, even if the original formulation is more complex than the current form .
