Transformer and genrator PF depends on the nature of
connected load ( Motor ), But motor has its own fixed Power
factor

Therefore Transformer and genrator capacity shown in KVA (
Without PF ) and motor Capacity shows in Kw ( with power
factor )

I have 2 KW electric water heater.I am gonna use it in controlling water temp.so I needed to increase or decrease the heating capacity.is there any electrical-electronic circuit for varying the resistance & so current?
