A residental apartment has
8 lamp of each of resistance 960ohm
3 ceiling fan each of impedance 345< 53.13 degrees (phasor)
2 air-con each of impedance of (48 + 36j)
Q is to determine the equivalent impedance.
I got the WRONG answer after I have separated everything into real and imaginery part and added many together. why?
Z real = (8*960)+ 3(345 cos 53.13) + 2*48
Z imaginery = 3(345 cos 53.13) + 2*36
I put them together and express them in phasor form.
Why am I wrong?
