Allows sizing but not only, for electric cables starting from the interpolation of any parameter (P - I - V - R - cos Ø, voltage drop, cable length and conductor size). The result is immediate.
Calculation, power, electric motors - consumption in Watt - consumption in Ampere.
Elaborated that allows, through the color code of resistance, to calculate their value. Simply enter the colors. Valid for resistors 4, 5 and 6 bands. Just type the colors to get the final values.
Knowing only two data can be traced back to all the others concerned by the Ohm's law (voltage, current intensity, resistance, and power). AC and AC three-phase results are also reported. Moreover, cos φ cratteristic values are indicated
Elaborated that performs the calculation (monthly to yearly) accurate power consumption of each device (mainly for places of public use such bars, restaurants, etc.).
Just enter the voltage and phase shift (cos Ø) and you're done. For each cable you know how many kW can be transported (the formula used to long cables few dozen meters).
