Hi guys,
My lecturer sucks so could any brights sparks give us a hand with this problem....
A consumer has three identical loads, each with an impedance of 9+j12 ohms, connected in parallel across the 240V (rms) 50Hz mains.
Could you explain how I can find:
1. the complex power supplied by the mains.
2. the real (average) power supplied by the mains
3. the reactive power supplied by the mains
4. the magnitude of the current drawn from the mains
5. the power factor of the load and whether it is leading or lagging
Any help would be grateful coz all i've got in front of me is a load of formulae not having a clue what they all mean.....
Thanks
