Hey! I had a doubt, why do we have to convert the time to seconds in the "harder example"? but can't retain it as 3 minutes...

[@hadaazmer4935]

We need to use seconds in the formula becuz its the SI unit for time

Can we get a distinction by seeing your videos and practicing past papers?

[@jessicali3078]

Would I lose marks in the exam if I used Power=Work Done/Time taken instead of Power=Energy transferred/Time?
