    Using SWA cables in parallel

    Hi A job that I'm currently looking at requires a 300A 3ph supply to a unit. The cable will be 100m long so the calc comes out at 240mm2. This cable is to be pulled down a duct, the main issue is it's weight and size will be a battle. I'm thinking of running two 95mm2 in parallel that would make...

    RLC in Parallel - Calculating instead of Drawing

    Morning all, Last night at college we moved on to RLC circuits in parallel, the type you'd typically find in a fluorescent light to correct power factor. We drew out some parallelograms to work out the true current usage and power factor after adding a capacitor. The lecturer said that's all...

    Series parallel combination resistance.

    Just spotted this on my facebook feed :juggle2: and thought it may be a good exercise for people to have a go at. What is the total resistance (Rt) of the circuit? :book::)
