the question i am struggling with is this, im new to the calculating of things and am not sure where to start.
A two core cable supplies two loads from a 230v supply, the first load is 70m from the supply and takes a current of 40A, the second load is 100m from the supply and takes 20A. find the voltage across the second load if each core of the cable has a c.s.a of 25mm2, assuming resistivity is 17M ohm mm.
Thanks
