A NAPIT expert answers your technical question

As part of our ongoing support for apprentices across the UK, we’ve teamed up with the technical experts from NAPIT to help answer your questions.

his question recently came on from an apprentice named Josh.


I am stuck on this equation. Please can you help?

Determine the power factor for a 2kw load that draws 15A from a 230 V supply.


then W divided by VA            2000 W          3450 VA     ie: ( 15A x 230V )

        2000 W    =  0.57 pf

       3450 VA

We hope this helps.
