If you want help with the questions you need to:
post the complete question here
show what attempt you have made
say what it is you don't understand
Sorry I can't help with the answers.
a 230V electrical appliance has a power rating of 800W
a)i) calculate the energy transfer in the application in 1min ii) the current taken by the appliance
i know this must be a quite straight forward physics question but after 2 weeks of starting physics im not so sure which forumla i should be using for this, my confusion is that ive read that the energy transfer is equal to the work done W but in the question it already says '800W' isn't that the answer then??
