The maximum current flowing in a cable depends essentially on the surface temperature of the cable that must not exceed the maximum temperature of the electrical insulation. A house thread AWG12 has a current rating of 25 A, when coated with thermoplastic so that the maximum temperature of the insulation is less than 60 ° C. To verify these data the following conditions are used: - Ac = 3.31 mm2 (section of the cable) - hconv = 4 W /...

A current sensor is measuring the DC current that is flowing through a power circuit. The output of the current sensor is a raw voltage signal which varies according to the following equation V 2.50.02 Where I is the flowing current in A (value can be positive or negative). An engineer would like a microcontroller to be able to measure this current so that it can be used for control purposes. The available ADC is 12-bit in resolution and measures...
