Question
Why iron core losses are constant at all loads in a 
transformer ?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Iron Losses = (Kh x Phi^1.2 x F) Watt/M^3
Where Kh - Hysteresis Constant
Phi - Flux
F - Frequency

in above equation Kh, F are constant & Phi increase only 1 to 5% from No load to full Load. Hence Iron Losses are practically constant at all loads.

I do wonder why current is present in neutral wire?i check single phase lead current feeding air conditioner...on its phase its current was 10A while same was 10A in neutral...as we know in neutral voltage is zero so if voltage is zero then how current appears on amp meter? my second observation is (just imagination)when I touch phase wire it give me shock but when i touch neutral nothing happens although as above its carrying current(amps) third but with same logic...as in simple Alternate current sine curve there is + and there is negative peak.means every time phase changing so how come every time same phase and same neutral stand (pardon for english mistakes)   1
