Yeah I did something like that, and gave a fair bit of detail. I just wanted to make sure I got the marks, it's pretty likely that detail wasn't required.THanks for the quick post.
Thats similar to what I wrote, but i know some people who gave a lot of detail on loudspeakers, induction cooktops, cathode ray tubes in televisions, etc.
omfg! I didnt put a heading on... If they deduct marks for that, I will spaz out....the final mark given for a heading for your table
yep i remember losing a mark in my assessment for not including a heading
i used a speakerI kinda put what you guys said, but I focused more on the transformations,
i.e, 11KV from the power station -> 240V in the home;
Use: Audio and Visual entertainment.
Transformations: 240V from power outlet to internal step-up transformer which steps up the voltage to ~ 1000V. Heat and sound and light energy emitted.
Something to that effect.
Oh, and what constitutes as an appliance?
Dw, man i used a speaker to . yes its an appliance, if TV is one, why isnt a speaker?i used a speaker
i dont think thats an appliance
it said 3 different useful energies didnt it? you have said 2, mechanical and infrared/heatI did:
electric drill - electrical energy >> rotational kinetic energy of the drill bit
a kettle - electrical energy >> thermal heat energy of element
a toaster - electrical energy >> thermal heat energy of element
a hair dryer - electrical energy >> thermal heat energy + rotational kinetic energy of fan inside
But I didn't even realise I put four until it was pens down :/ hope they aren't harsh about that
