    Okay, back to School Electronics, Given below is a parallel circuit with two diodes, the input current source is 5 A. And the connected resistor is 20 ohms. The circuit is a current divider (of course current divides in parallel). In case of simple current dividers we can solve it using the...

    My factory will install 75kW 3 Phase Motor (415V) and by using 3C x 35mm2 Armoured Cable. Based on IEC standard, is that the cable enough to withstand the maximum current produce from 75kW motor? Please attached the IEC data if available. Thanks.:)

    By now, I have 3 Phase motor (2.2KW) connected to 3 × 1.5 mm2 Cable. Then I want to replace it with the new motor which is 3KW. Is that 1.5 mm2 cable able to support the 3KW motor? I would like to know how to calculate the maximum allowable Ampere/KW flowing through the cable 3 × 1.5 mm2. Any...

    My business has recently added several 208V 70 amp breakers and I now have the task of reading it every month. I am using a clamp meter and am not sure how I should be calculating the total amperage in order to correctly charge our client. Any help would be greatly appreciated. Thanks
