Dear Edith Barrowman!
<div>W (for Watt) is defined as J/s (Joule per second). You can find additional info here lt;a href="https://en.wikipedia.org/wiki/Watt">https://en.wikipedia.org/wiki/Watt</a></div>
I am currently doing the CFPA diploma in fire management and I have submitted my answer to the above question exactly as you have above and the marker has come back with a response that I have my units tangled up and need to end up with joules per second. I am very confused. Can you please give my some guidance.
