I am confused about kva ratings on transformers. For example, suppose I have a transformer that has a 1 kva rating. I think this means that if I have a strictly resistive load then the load can be up to 1 kilowatt or 1 kva. But if I have an inductive load with a power factor of 80% then the load can not be more than .8 kva. Is this correct? Also does anyone know why va is used instead of watts? Thanks.
